Tapjoy studies have shown that mobile gamers prefer rewarded ads to interstitials 4-to-1. It’s a valuable insight for advertisers and developers alike when it comes maximizing ad revenue, but rewarded ads also have the potential to impact other parts of the user experience and your game’s performance overall.To ensure a healthy portfolio, it’s critical that developers understand the additional impact rewarded ads have beyond ad revenue. This includes their effect on metrics like in-app purchase conversion rate, average user spend, 30-day retention, and daily session count. To find out more, we conducted an in-depth analysis of eight different high-DAU apps across iOS and Android for several varying timeframes to find out how users behave when exposed to rewarded ads compared to those who aren’t.Higher IAP conversion ratesWe studied new app users during a one month period and segmented them into two different groups: Those who engaged with at least one rewarded ad and those who never engaged with an ad. We then compared the IAP conversion ratesfor each group.On average, users who engage with rewarded ads are 4.5 times more likely to make in-app purchase versus those who do not.7 out of the 8 of apps studied demonstrated higher conversion rates among those who engaged with ads versus those who did not.In the case of two of the apps studies, we found that users who engaged with an ad were over 9 times more likely to make a purchase.Higher average spend per userWe measured the average spend per user in each app for seven days before and seven days after a user’s first rewarded ad engagement.In all 8 apps studied, user spend increased significantly after they engaged with an ad. The average weighted increase in user spend was 326%. Among the apps studied, the boost in average spend per user ranged from just shy of 200% to over 500%.Increased 30-day retentionWe measured the 30-day retention rates of users who engaged with 1-6 rewarded ads during their first week of using an app. Three types of rewarded ad formats were studiedand measured against the average 30-day retention benchmark for all apps.Players who complete just one rewarded ad in the first week — whether a video, full-screen interstitial or an offerwall engagement — have a retention rate of at least 50%, compared to the benchmark of 13%.Rewarded video has the most profound effect on retention of any ad type. 30-day retention steadily increases with each video view, ranging from 53% to 68%, which is 3.5-5 times greater than the benchmark.Higher average daily session countWe measured the average number of user sessions per day — both seven days before and seven days after a user’s first rewarded ad engagement — for each high-DAU app.In all cases, users engaged with apps more frequently after completing a rewarded ad.All 8 apps studied demonstrated a lift in the average number of user sessions among those who completed an ad.The average weighted increase in user sessions across all apps was 34%.What does this mean for developers?4 key monetization strategies became abundantly clear following our research:Make rewarded ads easy to find – To increase visibility, consider adding a button to your app’s home screen or storefront, or utilize in-app messaging or push notifications to promote rewarded offers. Tapjoy’s Native-to-Earn, Message-to-Earn, and Push-to-Earn features make it easy for developers to add and manage these additions right from the dashboard.Explore currency sale promotions – Try running limited-time offers in which your players earn more currency than usual for every rewarded ad they complete. These currency sales can drive serious spikes in revenue. With Tapjoy, it’s easy to personalize your currency sale with custom branding and to control the payout ratio.Introduce ads early – Getting users to interact with ads early in their gameplay increases the chance that they will continue to engage with or make a purchase in your app. Rewarded ads introduce players to the mechanics and benefits of your in-app currency, so it’s important to make ads visible and easy to access during the player’s first few sessions.Integrate multiple rewarded formats – Integrating multiple formats — such as rewarded video and offerwall combined — provides developers with the best opportunity to monetize their users and maximize revenue. Diversifying formats not only unlocks higher eCPMs, but it provides players with the freedom to pick and choose the rewarded offer that appeals most to them. #understanding #impact #rewarded #ads #iap

More enterprises have moved to pay-for-performance salary and promotion models that measure progress toward goals -- but how do you measure goals for a maintenance programmer who barrels through a request backlog but delivers marginal value for the business, or for a business analyst whose success is predicated on forging intangibles like trust and cooperation with users so things can get done? It’s an age-old question facing companies, now that 77% of them use some type of pay-for-performance model. What are some popular pay-for-performance use cases? A factory doing piece work that pays employees based upon the number of items they assemble. A call center that pays agents based on how many calls they complete per day. A bank teller who gets rewarded for how many customers they sign up for credit cards. An IT project team that gets a bonus for completing a major project ahead of schedule. The IT example differs from the others, because it depends on team and not individual execution, but there nevertheless is something tangible to measure. The other use cases are more clearcut -- although they don’t account for pieces in the plant that were poorly assembled in haste to make quota and had to be reworked, or a call center agent who pushes calls off to someone else so they can end their calls in six minutes or less, or the teller who signs up X number of customers for credit cards, although two-thirds of them never use the credit card they signed up for. Related:In short, there are flaws in pay-for-performance models just as there are in other types of compensation models that organizations use. So, what’s the best path for IT for CIOs who want to implement pay for performance? One approach is to measure pay for performance based upon four key elements: hard results, effort, skill, and communications. The mix of these elements will vary, depending on the type of position each IT staff member performs. Here are two examples of pay per performance by position: 1. Computer maintenance programmers and help desk specialists Historically, IT departments have used hard numbers like how many open requests a computer maintenance programmer has closed, or how many calls a help desk employee has solved. There is merit in using hard results, and hard results should be factored into performance reviews for these individuals -- but hard numbers don’t tell the whole story.  For example, how many times has a help desk agent gone the extra mile with a difficult user or software bug, taking the time to see the entire process through until it is thoroughly solved? lf the issue was of a global nature, did the Help Desk agent follow up by letting others who use the application know that a bug was fixed? For the maintenance programmer who has completed the most open requests, which of these requests really solved a major business pain point? For both help desk and maintenance programming employees, were the changes and fixes properly documented and communicated to everyone with a need to know? And did these employees demonstrate the skills needed to solve their issues? Related:It’s difficult to capture hard results on elements like effort, communication and skills, but one way to go about it is to survey user departments on individual levels of service and effectiveness. From there, it’s up to IT managers to determinate the “mix” of hard results, effort, communication and skills on which the employee will be evaluated, and to communicate upfront to the employee what the pay for performance assessment will be based on. 2. Business analysts and trainers Business analysts and trainers are difficult to quantify in pay for performance models because so much of their success depends upon other people. A business analyst can know everything there is to know about a particular business area and its systems, but if the analyst is working with unresponsive users, or lacks the soft skills needed to communicate with users, the pay for performance can’t be based upon the technology skillset alone.  Related:IT trainers face a somewhat different dilemma when it  comes to performance evaluation: they can produce the training that new staff members need before staff is deployed on key projects,  but if a project gets delayed and this causes trainees to lose the knowledge that they learned, there is little the trainer can do aside from offering a refresher course. Can pay for performance be used for positions like these? It’s a mixed answer. Yes, pay per performance can be used for trainers, based upon how many individuals the trainer trains and how many new courses the trainer obtains or develops. These are the hard results. However, since so much of training’s execution depends upon other people downstream, like project managers who must start projects on time so new skills aren’t lost,  managers of training should also consider pay for performance elements such as effort, skills and communication.  In sum, for both business analysts and trainers, there are hard results that can be factored into a pay for performance formula, but there is also a need to survey each position’s “customers” -- those individualswho utilized the business analyst’s or trainer’s skills and products to accomplish their respective objectives in projects and training. Were these user-customers satisfied?  Summary Remarks The value that IT employees contribute to overall IT and to the business at large is a combination of tangible and intangible results. Pay for performance models are well suited to gauge tangible outcomes, but they fall short when it comes to the intangibles that could be just as important. Many years ago, when Pat Riley was coaching the Los Angeles Lakers, an interviewer asked what type of metrics he used when he measured the effectiveness of individual players on the basketball court. Was it the number of points, rebounds, or assists? Riley said he used an “effort" index. For example, how many times did a player go up to get a rebound, even if he didn’t end up with the ball? Riley said the effort individual players exhibited mattered, because even if they didn’t get the rebound, they were creating situations so someone else on the team could. IT is similar. It’s why OKR International, a performance consultancy, stated “Intangibles often create or destroy value quietly -- until their impact is too big to ignore. In the long run, they are the unseen levers that determine whether strategy thrives or withers.”  What CIOs and IT leadership can do when they use pay for performance is to assure that hard results, effort, communications and skills are appropriately blended for each IT staff position, and its responsibilities and realities -- because you can’t attach a numerical measurement to everything -- but you can observe visible changes that begin to manifest when a business analyst turns around what has been a hostile relationship with a user department and you begin to get things done.  #pay #performance #how #you #measure

All images courtesy of Mario Moore and Library Street Collective, shared with permission Mario Moore’s Oil Paintings Bridge Past and Present to Spotlight Black Resilience and Style June 4, 2025 Kate Mothes In large-scale works in oil, Detroit-based artist Mario Moore taps into the legacy of European painting traditions to create bold portraits exploring the nature of veneration, self-determination, and the continuum of history. Moore’s work is currently on view in Beneath Our Feet at Library Street Collective alongside fellow Detroiter LaKela Brown. His new pieces nod to the Dutch and Flemish tradition of devotional painting, particularly religious garland paintings. Within elegant arrangements of flowers and foliage, he highlights Black figures relaxing or tending to gardens. “The Patron Saint of Urban Farming”, oil on linen, 72 x 48 inches In “Watermelon Man,” a stone altar is surrounded by hibiscus and watermelons, both symbols of resilience. Historically, the latter represented self-sufficiency and freedom for Southern African Americans following Emancipation, but whites flipped the narrative into a stereotypical exemplar of poverty. Moore reclaims the fruit in the spirit of refined 17th-century still-lifes. The artist has long drawn on the culture and legacies of both Detroit and the U.S. more broadly through the lens of the Black diaspora. Earlier works like “Pillars” position Black figures in elegant dress within the vast wildernesses of the American frontier, bridging the past to explore how racial divisions continue to shape the present. An exhibition last summer at Grand Rapids Art Museum titled Revolutionary Times took his series A New Republic as a starting point, revisiting the history of Black Union soldiers during the Civil War. Moore learned that one of his ancestors, who had been enslaved as a child, later enlisted in the Union Army, spurring the artist’s exploration of the seminal mid-19th-century period of conflict and Western colonization. He positions present-day figures in contemporary dress within historical contexts, interrogating political and racial segregations. “Watermelon Man”, oil on linen, 51 1/2 x 42 inches Through tropes of European painting like a self-portrait of the artist in mirrored reflections and poses in three-quarter profile, Moore renders individuals whose direct, confident gazes and elegant dress invoke Detroit style and pride. For Beneath Our Feet, Brown and Moore collaborated on a five-foot-wide bas-relief bronze coin. Each artist completed one side, with Mario’s contribution taking the form of a portrait of Brown. “Her profile echoes the conventional format of traditional American coinage, confronting the historic absence of Black women in national symbolism and positions of authority,” the gallery says. On the opposite side, Brown depicts a bouquet of collard greens symbolic of nourishment and community. For this exhibition, Brown and Moore “reflect on the wealth held in the earth beneath us—and the enduring question of who holds the rights to till, own, and shape that land,” says an exhibition statement. Detroit is home to ambitious urban gardening initiatives that aim for local food sovereignty, mirroring the resourcefulness of Black farmers throughout history. The artists “consider land not just as property but as history, inheritance, and possibility,” the gallery says. Beneath Our Feet continues through July 30 in Detroit.

The transformation of Hangzhou’s old steelworks into a park is a tribute to China’s industrial past in a city of the future The congressional hearing about Chinese AI engine DeepSeek held in the US this April has propelled Hangzhou, the heart of China’s new digital economy, to the headlines. With companies such as DeepSeek, Unitree and Alibaba – whose payment app allowed me to get on the metro without needing to buy a ticket – headquartered in Hangzhou, China’s future in AI, robotics and automation is emanating from this city. Getting off the metro in the suburban area of Gongshu, the sun was shining on an old steelworks, overgrown with vines and flowers now that it is being transformed by Jiakun Architects and TLS Landscape Architecture into the Grand Canal Steelworks Park. The unfolding trade war might help to accelerate China’s journey into an automated future, leaving the world of factories behind, yet this new public space shows an impulse to commemorate the country’s economic history, and the forces that have shaped its contemporary built environment. Starting in Hangzhou and travelling more than 1,700km to Beijing, the Grand Canal is an engineering project built 2,500 years ago to connect the different regions of eastern China. The country’s geography means rivers flow from west to east: from higher elevations, culminating in the Himalayas, to the basin that is the country’s eastern seaboard. Historically, it was difficult to transport goods from mercantile centres in the south, including Hangzhou and Suzhou, to the political centre in Beijing up north. As a civil engineering project, the Grand Canal rivals the Great Wall, but if the Great Wall aims to protect China from the outside, the Grand Canal articulates Chinese commerce from the inside. The historic waterway has been an important conduit of economic and cultural exchange, enabling the movement of people and goods such as grain, silk, wine, salt and gravel across the country. It became a UNESCO World Heritage site in 2014. The state‑owned enterprise collective was founded, and the physical facility of Hangzhou steelworks built, in the 1950s during the Great Leap Forward, when China strove for self‑sufficiency, and wended its way through the country’s economic trajectory: first the economic chaos of the 1960s, then the reforms and opening up in the 1980s. Steel remains an important industry today in China, home to more than half of the world’s production, but the listing of the Grand Canal enabled city leaders to move production to a new site and decommission the Hangzhou steelworks. External mandates, including entry into the World Trade Organization, the Beijing Olympics and UNESCO listings, have been instrumentalised in the country to pursue a range of internal interests, particularly economical and real estate ones.  In 2016, the factory was shut down in 150 days, in what the company describes as a ‘heroic’ effort, and the site attracted tourists of industrial ruins. In the competition brief, Hangzhou planners asked for ‘as much of the existing blast furnaces and buildings’ as possible to be preserved. When I arrived in China in 2008, Chinese cities were notorious for heritage demolition, but today urban planners and architects increasingly work to preserve historical buildings. Just like several industrial sites in Beijing and Shanghai have been transformed into major public and cultural spaces in the past decade, in the Yangtze River Delta – of which Hangzhou is a major hub – several industrial sites along the Grand Canal’s course are being given a new lease of life. Today, the three blast furnaces of Hangzhou steelworks remain, with the silhouettes of their smokestacks easily recognisable from a distance. The project preserves as much as possible of the aesthetics of a steel mill with none of the danger or dust, ready to welcome instead new community facilities and cultural programmes in a vast and restored piece of landscape. Situated in a former working‑class district that has been gentrifying and welcoming young families, the new park is becoming a popular venue for music festivals, flower viewing in springtime and year‑round picnics – when I visited, parents were teaching their children to ride a bicycle, and students from Zhejiang University, about a kilometre from the park, were having lunch on the grass. New programmes accommodated in the old coke oven and steel mills will include a series of exhibition halls and spaces welcoming a wide range of cultural and artistic workshops as well as events – the project’s first phase has just completed but tenant organisations have not yet moved in, and works are ongoing to the north of the park. On the day of my visit, a student art exhibition was on display near one of the furnaces, with works made from detritus from the site, including old packing containers. The rehabilitated buildings also provide a range of commercial units, where cafés, restaurants, shops, a bookshop, ice cream shop and a gym have already opened their doors to visitors.  Several structures were deemed structurally unsafe and required demolition, such as the old iron casting building. The architects proposed to partially reconstruct it on its original footprint; the much more open structure, built with reclaimed bricks, now houses a semi‑outdoor garden. Material choices evoke the site’s industrial past: weathered steel, exposed concrete and large expanses of glazing dominate the landscape. The widespread use of red, including in an elevated walkway that traverses the park – at times vaguely reminiscent of a Japanese torii gate in the space below – gives a warm and reassuring earthiness to the otherwise industrial colour palette. Elements selected by the designers underwent sanitisation and detoxification before being reused. The landscaping includes old machinery parts and boulders; recuperated steel panels are for instance inlaid into the paving while pipes for pouring molten steel have been turned into a fountain. The train tracks that once transported material continue to run through the site, providing paths in between the new patches of vegetation, planted with local grasses as well as Japanese maples, camphors and persimmon trees. As Jiawen Chen from TLS describes it, the aesthetic feels ‘wild, but not weedy or abandoned’. The landscape architects’ inspiration came from the site itself after the steelworks’ closure, she explains, once vegetation had begun to reclaim it. Contaminated soil was replaced with clean local soil – at a depth between 0.5 and 1.5 metres, in line with Chinese regulations. The removed soil was sent to specialised facilities for purification, while severely contaminated layers were sealed with concrete. TLS proposed phytoremediationin selected areas of the site ‘as a symbolic and educational gesture’, Chen explains, but ‘the client preferred to be cautious’. From the eastern end of the park, hiking trails lead to the mountain and its Buddhist temples. The old steel mill’s grounds fade seamlessly into the hills. Standing in what it is still a construction site, a sign suggests there will soon be a rowing centre here.  While Jiakun Architects and TLS have prioritised making the site palatable as a public space, the project also brings to life a history that many are likely to have forgotten. Throughout, the park incorporates different elements of China’s economic history, including the life of the Grand Canal and the industrial era. There is, for example, a Maoist steelworker painted on the mural of one of the cafés, as well as historical photographs and drawings of the steelworks peppering the site, framed and hung on the walls. The ambition might be in part to pay homage to steelworkers, but it is hard to imagine them visiting. Gongshu, like the other suburbs of Hangzhou, has seen rapid increases in its property prices.  The steelworks were built during the Maoist era, a time of ‘battling with earth, battling with heaven, battling with humanity’, to borrow Mao’s own words. Ordinary people melted down pots and pans to surpass the UK in steel production, and industry was seen as a sharp break from a traditional Chinese way of life, in which humans aspire to live in harmony with their environment. The priorities of the government today are more conservative, seeking to create a garden city to attract engineers and their families. Hangzhou has long represented the balmy and sophisticated life of China’s south, a land of rice and fish. To the west of the city, not far from the old steelworks, are the ecologically protected Xixi wetlands, and Hangzhou’s urban planning exemplifies the Chinese principle of 天人合一, or nature and humankind as one.  Today, Hangzhou is only 45 minutes from Shanghai by high‑speed train. The two cities feel like extensions of one another, an urban region of 100 million people. The creation of the Grand Canal Steelworks Park reflects the move away from heavy industry that Chinese cities such as Hangzhou are currently making, shifting towards a supposedly cleaner knowledge‑driven economy. Yet the preservation of the steelworks epitomises the sentimental attitude towards the site’s history and acts as a reminder that today’s middle classes are the children of yesterday’s steelworkers, drinking coffee and playing with their own children in grassy lawns next to shuttered blast furnaces.  The park’s second phase is already nearing completion, and the competition for the nearby Grand Canal Museum was won by Herzog & de Meuron in 2020 – the building is under construction, and should open at the end of this year. It is a district rich in history, but the city is resolutely turned towards the future.  2025-06-02 Reuben J Brown Share AR May 2025CircularityBuy Now #steel #life #grand #canal #steelworks

After detailing the VFX work on The Last of Us Season 1 in 2023, Alex Wang returns to reflect on how the scope and complexity have evolved in Season 2. With close to 30 years of experience in the visual effects industry, Fiona Campbell Westgate has contributed to major productions such as Ghost in the Shell, Avatar: The Way of Water, Ant-Man and the Wasp: Quantumania, and Nyad. Her work on Nyad earned her a VES Award for Outstanding Supporting Visual Effects in a Photoreal Feature. Collaboration with Craig Mazin and Neil Druckmann is key to shaping the visual universe of The Last of Us. Can you share with us how you work with them and how they influence the visual direction of the series? Alex Wang // Craig visualizes the shot or scene before putting words on the page. His writing is always exceptionally detailed and descriptive, ultimately helping us to imagine the shot. Of course, no one understands The Last of Us better than Neil, who knows all aspects of the lore very well. He’s done much research and design work with the Naughty Dog team, so he gives us good guidance regarding creature and environment designs. I always try to begin with concept art to get the ball rolling with Craig and Neil’s ideas. This season, we collaborated with Chromatic Studios for concept art. They also contributed to the games, so I felt that continuity was beneficial for our show. Fiona Campbell Westgate // From the outset, it was clear that collaborating with Craig would be an exceptional experience. Early meetings revealed just how personable and invested Craig is. He works closely with every department to ensure that each episode is done to the highest level. Craig places unwavering trust in our VFX Supervisor, Alex Wang. They have an understanding between them that lends to an exceptional partnership. As the VFX Producer, I know how vital the dynamic between the Showrunner and VFX Supervisor is; working with these two has made for one of the best professional experiences of my career.  Photograph by Liane Hentscher/HBO How has your collaboration with Craig evolved between the first and second seasons? Were there any adjustments in the visual approach or narrative techniques you made this season? Alex Wang // Since everything was new in Season 1, we dedicated a lot of time and effort to exploring the show’s visual language, and we all learned a great deal about what worked and what didn’t for the show. In my initial conversations with Craig about Season 2, it was clear that he wanted to expand the show’s scope by utilizing what we established and learned in Season 1. He felt significantly more at ease fully committing to using VFX to help tell the story this season. The first season involved multiple VFX studios to handle the complexity of the effects. How did you divide the work among different studios for the second season? Alex Wang // Most of the vendors this season were also in Season 1, so we already had a shorthand. The VFX Producer, Fiona Campbell Westgate, and I work closely together to decide how to divide the work among our vendors. The type of work needs to be well-suited for the vendor and fit into our budget and schedule. We were extremely fortunate to have the vendors we did this season. I want to take this opportunity to thank Weta FX, DNEG, RISE, Distillery VFX, Storm Studios, Important Looking Pirates, Blackbird, Wylie Co., RVX, and VDK. We also had ILM for concept art and Digital Domain for previs. Fiona Campbell Westgate // Alex Wang and I were very aware of the tight delivery schedule, which added to the challenge of distributing the workload. We planned the work based on the individual studio’s capabilities, and tried not to burden them with back to back episodes wherever possible. Fortunately, there was shorthand with vendors from Season One, who were well-acquainted with the process and the quality of work the show required. The town of Jackson is a key location in The Last of Us. Could you explain how you approached creating and expanding this environment for the second season? Alex Wang // Since Season 1, this show has created incredible sets. However, the Jackson town set build is by far the most impressive in terms of scope. They constructed an 822 ft x 400 ft set in Minaty Bay that resembled a real town! I had early discussions with Production Designer Don MacAulay and his team about where they should concentrate their efforts and where VFX would make the most sense to take over. They focused on developing the town’s main street, where we believed most scenes would occur. There is a big reveal of Jackson in the first episode after Ellie comes out of the barn. Distillery VFX was responsible for the town’s extension, which appears seamless because the team took great pride in researching and ensuring the architecture aligned with the set while staying true to the tone of Jackson, Wyoming. Fiona Campbell Westgate // An impressive set was constructed in Minaty Bay, which served as the foundation for VFX to build upon. There is a beautiful establishing shot of Jackson in Episode 1 that was completed by Distillery, showing a safe and almost normal setting as Season Two starts. Across the episodes, Jackson set extensions were completed by our partners at RISE and Weta. Each had a different phase of Jackson to create, from almost idyllic to a town immersed in Battle.  What challenges did you face filming Jackson on both real and virtual sets? Was there a particular fusion between visual effects and live-action shots to make it feel realistic? Alex Wang // I always advocate for building exterior sets outdoors to take advantage of natural light. However, the drawback is that we cannot control the weather and lighting when filming over several days across two units. In Episode 2, there’s supposed to be a winter storm in Jackson, so maintaining consistency within the episode was essential. On sunny and rainy days, we used cranes to lift large 30x60ft screens to block the sun or rain. It was impossible to shield the entire set from the rain or sun, so we prioritized protecting the actors from sunlight or rain. Thus, you can imagine there was extensive weather cleanup for the episode to ensure consistency within the sequences. Fiona Campbell Westgate // We were fortunate that production built a large scale Jackson set. It provided a base for the full CG Jackson aerial shots and CG Set Extensions. The weather conditions at Minaty Bay presented a challenge during the filming of the end of the Battle sequence in Episode 2. While there were periods of bright sunshine, rainfall occurred during the filming of the end of the Battle sequence in Episode 2. In addition to the obvious visual effects work, it became necessary to replace the ground cover. Photograph by Liane Hentscher/HBO The attack on Jackson by the horde of infected in season 2 is a very intense moment. How did you approach the visual effects for this sequence? What techniques did you use to make the scale of the attack feel as impressive as it did? Alex Wang // We knew this would be a very complex sequence to shoot, and for it to be successful, we needed to start planning with the HODs from the very beginning. We began previs during prep with Weta FX and the episode’s director, Mark Mylod. The previs helped us understand Mark and the showrunner’s vision. This then served as a blueprint for all departments to follow, and in many instances, we filmed the previs. Fiona Campbell Westgate // The sheer size of the CG Infected Horde sets the tone for the scale of the Battle. It’s an intimidating moment when they are revealed through the blowing snow. The addition of CG explosions and atmospheric effects contributed in adding scale to the sequence.  Can you give us an insight into the technical challenges of capturing the infected horde? How much of the effect was done using CGI, and how much was achieved with practical effects? Alex Wang // Starting with a detailed previs that Mark and Craig approved was essential for planning the horde. We understood that we would never have enough stunt performers to fill a horde, nor could they carry out some stunts that would be too dangerous. I reviewed the previs with Stunt Coordinator Marny Eng numerous times to decide the best placements for her team’s stunt performers. We also collaborated with Barrie Gower from the Prosthetics team to determine the most effective allocation of his team’s efforts. Stunt performers positioned closest to the camera would receive the full prosthetic treatment, which can take hours. Weta FX was responsible for the incredible CG Infected horde work in the Jackson Battle. They have been a creative partner with HBO’s The Last of Us since Season 1, so they were brought on early for Season 2. I began discussions with Weta’s VFX supervisor, Nick Epstein, about how we could tackle these complex horde shots very early during the shoot. Typically, repetition in CG crowd scenes can be acceptable, such as armies with soldiers dressed in the same uniform or armour. However, for our Infected horde, Craig wanted to convey that the Infected didn’t come off an assembly line or all shop at the same clothing department store. Any repetition would feel artificial. These Infected were once civilians with families, or they were groups of raiders. We needed complex variations in height, body size, age, clothing, and hair. We built our base library of Infected, and then Nick and the Weta FX team developed a “mix and match” system, allowing the Infected to wear any costume and hair groom. A procedural texturing system was also developed for costumes, providing even greater variation. The most crucial aspect of the Infected horde was their motion. We had numerous shots cutting back-to-back with practical Infected, as well as shots where our CG Infected ran right alongside a stunt horde. It was incredibly unforgiving! Weta FX’s animation supervisor from Season 1, Dennis Yoo, returned for Season 2 to meet the challenge. Having been part of the first season, Dennis understood the expectations of Craig and Neil. Similar to issues of model repetition within a horde, it was relatively easy to perceive repetition, especially if they were running toward the same target. It was essential to enhance the details of their performances with nuances such as tripping and falling, getting back up, and trampling over each other. There also needed to be a difference in the Infected’s running speed. To ensure we had enough complexity within the horde, Dennis motion-captured almost 600 unique motion cycles. We had over a hundred shots in episode 2 that required CG Infected horde. Fiona Campbell Westgate // Nick Epstein, Weta VFX Supervisor, and Dennis Yoo, Weta Animation Supervisor, were faced with having to add hero, close-up Horde that had to integrate with practical Stunt performers. They achieved this through over 60 motion capture sessions and running it through a deformation system they developed. Every detail was applied to allow for a seamless blend with our practical Stunt performances. The Weta team created a custom costume and hair system that provided individual looks to the CG Infected Horde. We were able to avoid the repetitive look of a CG crowd due to these efforts. The movement of the infected horde is crucial for the intensity of the scene. How did you manage the animation and simulation of the infected to ensure smooth and realistic interaction with the environment? Fiona Campbell Westgate // We worked closely with the Stunt department to plan out positioning and where VFX would be adding the CG Horde. Craig Mazin wanted the Infected Horde to move in a way that humans cannot. The deformation system kept the body shape anatomically correct and allowed us to push the limits from how a human physically moves.  The Bloater makes a terrifying return this season. What were the key challenges in designing and animating this creature? How did you work on the Bloater’s interaction with the environment and other characters? Alex Wang // In Season 1, the Kansas City cul-de-sac sequence featured only a handful of Bloater shots. This season, however, nearly forty shots showcase the Bloater in broad daylight during the Battle of Jackson. We needed to redesign the Bloater asset to ensure it looked good in close-up shots from head to toe. Weta FX designed the Bloater for Season 1 and revamped the design for this season. Starting with the Bloater’s silhouette, it had to appear large, intimidating, and menacing. We explored enlarging the cordyceps head shape to make it feel almost like a crown, enhancing the Bloater’s impressive and strong presence. During filming, a stunt double stood in for the Bloater. This was mainly for scale reference and composition. It also helped the Infected stunt performers understand the Bloater’s spatial position, allowing them to avoid running through his space. Once we had an edit, Dennis mocapped the Bloater’s performances with his team. It is always challenging to get the motion right for a creature that weighs 600 pounds. We don’t want the mocap to be overly exaggerated, but it does break the character if the Bloater feels too “light.” The brilliant animation team at Weta FX brought the Bloater character to life and nailed it! When Tommy goes head-to-head with the Bloater, Craig was quite specific during the prep days about how the Bloater would bubble, melt, and burn as Tommy torches him with the flamethrower. Important Looking Pirates took on the “Burning Bloater” sequence, led by VFX Supervisor Philip Engstrom. They began with extensive R&D to ensure the Bloater’s skin would start to bubble and burn. ILP took the final Bloater asset from Weta FX and had to resculpt and texture the asset for the Bloater’s final burn state. Craig felt it was important for the Bloater to appear maimed at the end. The layers of FX were so complex that the R&D continued almost to the end of the delivery schedule. Fiona Campbell Westgate // This season the Bloater had to be bigger, more intimidating. The CG Asset was recreated to withstand the scrutiny of close ups and in daylight. Both Craig Mazin and Neil Druckmann worked closely with us during the process of the build. We referenced the game and applied elements of that version with ours. You’ll notice that his head is in the shape of crown, this is to convey he’s a powerful force.  During the Burning Bloater sequence in Episode 2, we brainstormed with Philip Engström, ILP VFX Supervisor, on how this creature would react to the flamethrower and how it would affect the ground as it burns. When the Bloater finally falls to the ground and dies, the extraordinary detail of the embers burning, fluid draining and melting the surrounding snow really sells that the CG creature was in the terrain.  Given the Bloater’s imposing size, how did you approach its integration into scenes with the actors? What techniques did you use to create such a realistic and menacing appearance? Fiona Campbell Westgate // For the Bloater, a stunt performer wearing a motion capture suit was filmed on set. This provided interaction with the actors and the environment. VFX enhanced the intensity of his movements, incorporating simulations to the CG Bloater’s skin and muscles that would reflect the weight and force as this terrifying creature moves.  Seattle in The Last of Us is a completely devastated city. Can you talk about how you recreated this destruction? What were the most difficult visual aspects to realize for this post-apocalyptic city? Fiona Campbell Westgate // We were meticulous in blending the CG destruction with the practical environment. The flora’s ability to overtake the environment had to be believable, and we adhered to the principle of form follows function. Due to the vastness of the CG devastation it was crucial to avoid repetitive effects. Consequently, our vendors were tasked with creating bespoke designs that evoked a sense of awe and beauty. Was Seattle’s architecture a key element in how you designed the visual effects? How did you adapt the city’s real-life urban landscape to meet the needs of the story while maintaining a coherent aesthetic? Alex Wang // It’s always important to Craig and Neil that we remain true to the cities our characters are in. DNEG was one of our primary vendors for Boston in Season 1, so it was natural for them to return for Season 2, this time focusing on Seattle. DNEG’s VFX Supervisor, Stephen James, who played a crucial role in developing the visual language of Boston for Season 1, also returns for this season. Stephen and Melaina Maceled a team to Seattle to shoot plates and perform lidar scans of parts of the city. We identified the buildings unique to Seattle that would have existed in 2003, so we ensured these buildings were always included in our establishing shots. Overgrowth and destruction have significantly influenced the environments in The Last of Us. The environment functions almost as a character in both Season 1 and Season 2. In the last season, the building destruction in Boston was primarily caused by military bombings. During this season, destruction mainly arises from dilapidation. Living in the Pacific Northwest, I understand how damp it can get for most of the year. I imagined that, over 20 years, the integrity of the buildings would be compromised by natural forces. This abundant moisture creates an exceptionally lush and vibrant landscape for much of the year. Therefore, when designing Seattle, we ensured that the destruction and overgrowth appeared intentional and aesthetically distinct from those of Boston. Fiona Campbell Westgate // Led by Stephen James, DNEG VFX Supervisor, and Melaina Mace, DNEG DFX Supervisor, the team captured photography, drone footage and the Clear Angle team captured LiDAR data over a three-day period in Seattle. It was crucial to include recognizable Seattle landmarks that would resonate with people familiar with the game.  The devastated city almost becomes a character in itself this season. What aspects of the visual effects did you have to enhance to increase the immersion of the viewer into this hostile and deteriorated environment? Fiona Campbell Westgate // It is indeed a character. Craig wanted it to be deteriorated but to have moments where it’s also beautiful in its devastation. For instance, in the Music Store in Episode 4 where Ellie is playing guitar for Dina, the deteriorated interior provides a beautiful backdrop to this intimate moment. The Set Decorating team dressed a specific section of the set, while VFX extended the destruction and overgrowth to encompass the entire environment, immersing the viewer in strange yet familiar surroundings. Photograph by Liane Hentscher/HBO The sequence where Ellie navigates a boat through a violent storm is stunning. What were the key challenges in creating this scene, especially with water simulation and the storm’s effects? Alex Wang // In the concluding episode of Season 2, Ellie is deep in Seattle, searching for Abby. The episode draws us closer to the Aquarium, where this area of Seattle is heavily flooded. Naturally, this brings challenges with CG water. In the scene where Ellie encounters Isaac and the W.L.F soldiers by the dock, we had a complex shoot involving multiple locations, including a water tank and a boat gimbal. There were also several full CG shots. For Isaac’s riverine boat, which was in a stormy ocean, I felt it was essential that the boat and the actors were given the appropriate motion. Weta FX assisted with tech-vis for all the boat gimbal work. We began with different ocean wave sizes caused by the storm, and once the filmmakers selected one, the boat’s motion in the tech-vis fed the special FX gimbal. When Ellie gets into the Jon boat, I didn’t want it on the same gimbal because I felt it would be too mechanical. Ellie’s weight needed to affect the boat as she got in, and that wouldn’t have happened with a mechanical gimbal. So, we opted to have her boat in a water tank for this scene. Special FX had wave makers that provided the boat with the appropriate movement. Instead of guessing what the ocean sim for the riverine boat should be, the tech- vis data enabled DNEG to get a head start on the water simulations in post-production. Craig wanted this sequence to appear convincingly dark, much like it looks out on the ocean at night. This allowed us to create dramatic visuals, using lightning strikes at moments to reveal depth. Were there any memorable moments or scenes from the series that you found particularly rewarding or challenging to work on from a visual effects standpoint? Alex Wang // The Last of Us tells the story of our characters’ journey. If you look at how season 2 begins in Jackson, it differs significantly from how we conclude the season in Seattle. We seldom return to the exact location in each episode, meaning every episode presents a unique challenge. The scope of work this season has been incredibly rewarding. We burned a Bloater, and we also introduced spores this season! Photograph by Liane Hentscher/HBO Looking back on the project, what aspects of the visual effects are you most proud of? Alex Wang // The Jackson Battle was incredibly complex, involving a grueling and lengthy shoot in quite challenging conditions, along with over 600 VFX shots in episode 2. It was truly inspiring to witness the determination of every department and vendor to give their all and create something remarkable. Fiona Campbell Westgate // I am immensely proud of the exceptional work accomplished by all of our vendors. During the VFX reviews, I found myself clapping with delight when the final shots were displayed; it was exciting to see remarkable results of the artists’ efforts come to light.  How long have you worked on this show? Alex Wang // I’ve been on this season for nearly two years. Fiona Campbell Westgate // A little over one year; I joined the show in April 2024. What’s the VFX shots count? Alex Wang // We had just over 2,500 shots this Season. Fiona Campbell Westgate // In Season 2, there were a total of 2656 visual effects shots. What is your next project? Fiona Campbell Westgate // Stay tuned… A big thanks for your time.

A Deadly Disease Is Eating Away at Caribbean Corals and Wreaking Havoc on Reefs. Could Probiotics Be the Solution? New research suggests the probiotic McH1-7 could help stop the spread of stony coral tissue loss disease among wild corals near Fort Lauderdale, Florida Scientists determined the most effective method of halting the disease was covering a coral colony with a weighted plastic bag, then injecting a seawater solution that contains the probiotic. They left the colony covered for two hours to allow the probiotic bacteria to colonize the coral. Hunter Noren Probiotics can be good for human health. Now, new research suggests they might also help protect coral reefs. A bacterial probiotic helped slow the advance of stony coral tissue loss disease—a fast-spreading and deadly condition—among wild corals in Florida, researchers report today in a new study published in the journal Frontiers in Marine Science. The probiotic may be a good alternative to antibiotics like amoxicillin, which temporarily curb the spread of the disease but must be reapplied frequently. In addition, scientists fear stony coral tissue loss disease may one day become resistant to these antibiotic treatments—just as “superbugs” that infect humans are building resistance to our own drugs. Antibiotics are meant to kill microorganisms, but probiotics are beneficial living microbes. The idea is that a probiotic can be incorporated into corals’ natural microbiomes, ideally offering them longer-lasting protection. First discovered in Florida in 2014, stony coral tissue loss disease attacks the soft tissue of more than 30 different species of coral. Without treatment, the disease eventually kills the corals, and their soft tissue falls off, revealing the white calcium carbonate skeleton below. In just weeks or months, it can devastate a whole colony. Stony coral tissue loss disease can be spread by fish that eat coral, as well as by boaters and divers who do not disinfect their gear. The condition has since expanded its range beyond Florida to reefs throughout the Caribbean. Several years ago, researchers looking at the great star coral discovered a probiotic called Pseudoalteromonas sp. strain McH1-7. Laboratory tests showed McH1-7 stopped or slowed the progression of stony coral tissue loss disease in infected corals. It also helped prevent the disease from spreading to healthy corals. But that was in the lab. Would McH1-7 be similarly effective in the ocean? Researchers were eager to find out, so they set up an experiment on a shallow reef off the coast of Fort Lauderdale. Study co-author Kelly Pitts, a research technician with the Smithsonian Marine Station, applies a paste containing the probiotic directly onto the disease lesion of an infected coral. Hunter Noren Experimenting with wild corals For the study, the scientists focused on 40 great star coral colonies that were showing symptoms of stony coral tissue loss disease. In one experimental condition, the researchers made a paste that contained McH1-7 and applied it directly onto the disease lesions. For comparison, they also applied the same paste, minus the probiotic, to some corals. In another condition, they covered infected coral colonies with weighted plastic bags, then filled the bags with seawater solutions made with and without McH1-7. They left the corals covered for two hours. “This created a little mini-aquarium that kept the probiotics around each coral colony,” says study co-author Valerie Paul, head scientist at the Smithsonian Marine Station at Fort Pierce, Florida, in a statement. The scientists completed all the treatments within the first 4.5 months of the project. Then, they returned periodically to gather tissue and mucus samples from the corals to measure changes to their microbiomes. Over the next 2.5 years, they took photos from a variety of different angles, which they then used to create 3D models that could track the disease’s progression. In the end, the results suggest covering the corals with plastic bags filled with the probiotic seawater solution was the most effective method. More than two years post-treatment, the colonies that received the probiotic bag had lost just 7 percent of their tissue, while colonies in the control bag condition faced 35 percent tissue loss. Scientists applied a probiotic paste directly to disease lesions on some corals. Kelly Pitts The probiotic paste, by contrast, appears to have made the situation worse: The corals that had the probiotic paste applied directly to their lesions lost more tissue than those treated with the control paste, which did not contain McH1-7. “We do not really know what is going on with the probiotic paste treatment,” Paul tells Smithsonian magazine in an email. But she has a few theories. It’s possible the high concentrations of McH1-7 contributed to localized hypoxia, or low-oxygen conditions that further harmed the already stressed corals, she says. Or, the probiotic could have changed the microbiome at the lesion site in some negative way. Another possibility is that McH1-7 produces antibiotics or other substances that were harmful at high concentrations. Amanda Alker, a marine microbiologist at the University of Rhode Island who was not involved with the study, wonders if this finding suggests McH1-7 is beneficial at specific dosages—a question future laboratory research might be able to answer, she tells Smithsonian magazine in an email. She’s also curious to know which specific molecular components of the probiotic are responsible for the increased tissue loss when applied as a paste. More broadly, Alker would like to see additional experiments validating the bag treatment method, but she says this “inventive” technique seems promising. “Their approach is a safer solution than antibiotic treatment methods that have been deployed to combatin the field so far,” she says. “Further, this is a practical solution that could be implemented widely because it doesn’t require highly specialized equipment and has the ability to be used with any type of microbial solution.” Looking ahead to save reefs Probiotics are likely not a silver bullet for protecting corals. For one, researchers still don’t know exactly what causes stony coral tissue loss disease, which makes it difficult to determine how or why the probiotic works, Paul says. In addition, since the disease has spread to many different parts of the Caribbean, it might be challenging to use the bag treatment technique on all affected colonies. “We would need to develop better methods of deploying the probiotic through time release formulations or other ways to scale up treatments,” Paul says. “Right now, having divers swim around underwater with weighted bags is not a very scalable method.” The researchers have also conducted similar experiments on infected corals located farther south, in the Florida Keys. However, these tests have produced mixed results, probably because of regional differences in stony coral tissue loss disease. This is another hurdle scientists will likely need to overcome if they hope to expand the use of probiotics. “We probably need to develop different probiotics for different coral species and different regions of the Caribbean,” Paul says. Researchers returned to gather samples of tissues and mucus to see how the corals' microbiomes had changed. Hunter Noren Even so, scientists are heartened by the results of the experiments conducted near Fort Lauderdale. With more research, the findings suggest probiotics could be a promising tool for combatting the disease elsewhere. “Coral probiotics is a challenging field, because there are hundreds of different types of bacteria that associate with corals, and there are limitless experiments that need to be performed,” Amy Apprill, a marine chemist at Woods Hole Oceanographic Institution who was not involved with the research, tells Smithsonian magazine in an email. “These researchers made a major advance with their study by demonstrating the utility of whole colony treatment as well as the specific probiotic tested.” Apprill adds that, while antibiotics have been widely used to control stony coral tissue loss disease, scientists haven’t conducted much research to see how these treatments are affecting the plants and creatures that live nearby. “Using a naturally occurring bacterium for disease treatment may result in lessened impacts to other members of the coral reef ecosystem,” she says. Amid rising ocean temperatures, scientists expect to find even more diseased coral colonies in the future. Warmer waters may also allow other pathogens to thrive and proliferate. Against that backdrop, Apprill adds, probiotics and the different methods of applying them will be “major allies” in the fight to save coral reefs. Paul is also optimistic. Through research and field studies, she’s confident researchers will be able to develop interventions that can “help corals better survive changing environments and respond better to diseases and bleaching,” she says.
