A real-time tool for 3D visualization and virtual production Originally created by visualization studio KA-RA and acquired by Epic Games in 2019, Twinmotion is a real-time visualization tool for architectural, automotive and product design.It imports hero models in a range of 3D file formats, or via live links to CAD software, with users able to dress the scenes using a library of stock assets. Atmospheric properties – including clouds, rain and snow, and ambient lighting based on geographical location and time of day – can be adjusted via slider-based controls. The software is now free to indie artists and studios with revenue under $1 million/year, following Epic Games’ recent changes to the pricing of its products. Epic Games is also now increasingly pitching the software at the entertainment marked, as an ‘on-ramp’ to Unreal Engine for virtual production and real-time VFX. New 3D Grass Material for generating procedural grass on surfaces Twinmotion 2025.1.1 comes just two months after the major Twinmotion 2025.1 update, and is a much smaller release, but it does include some significant new features. One is the new 3D Grass Material, for quickly generating realistic grass in scenes. Assigning it to a surface generates procedural 3D grass that follows the contours of the surface, with options to set the type, length and color of the grass, and whether it is affected by wind. The material can currently only be applied to static objects, not animated surfaces, and comes with some limitations when using the new Lumen rendering mode. Support for DLSS 4 for better viewport performance on NVIDIA GPUs Other key changes include support for DLSS 4, the latest version of NVIDIA’s AI-based frame generation and image upscaling technology.The update should increase viewport frame rates on systems with NVIDIA GPUs. Other changes: new modeling tools, clay materials, and workflow updates Twinmotion 2025.1.1 also features updates to the software’s modeling tools, with a new Merge tool for combining objects, and a Split tool for splitting objects into parts.Workflow improvements include two new orbit modes for navigating the viewport, a new Camera Inertia setting for smoother viewport navigation, updates to the Edit pivot feature and XYZ panel, and the option to use millimetres as units for scene scale. In addition, 10 new clay materials have been added to the accompanying asset library. For users with paid subscriptions, Configurations – interactive 3D presentations showcasing a project – can now be exported to online collaboration platform Twinmotion Cloud. Price, system requirements and release date Twinmotion 2025.1.1 is compatible with Windows 10+ and macOS 12.5+. Integration plugins are available for CAD and DCC apps including 3ds Max 2017+, CityEngine 2022.0+ and SketchUp Pro 2019+. The software is free to users with gross annual revenue under $1 million/year. The free edition lacks access to Twinmotion Cloud, but is otherwise fully featured. For larger studios, subscriptions cost $445/seat/year.
