Additional smaller improvements in Corona 12 Update 2 General(3ds Max) Added support for Max 2026. Corona now detects 3ds Max environment effects and provides an option to delete them. Opening a scene which references assets from the material library, LUT presets or IES presets now automatically corrects path when the location of presets changed (e.g. when moving scene between macOS and Windows, or due to change of installation root as mentioned under ‘Installation Changes’). (Cinema 4D) The Cosmos dialog can now be docked in the Cinema 4D UI. Help dialog can now be docked in Cinema 4D UI also on Windows. Removed usage of temporary files when rendering via TR to avoid potential issues with disk space. Vantage(3ds Max and Cinema 4D) Improved how fast Live Link can be cancelled. Vantage export / Live Link now supports light visibility in reflections. VFB(3ds Max and Cinema 4D) VFB scrollbars are now brighter for better visibility. VFB history item thumbnails now update when edited. Enabled toggling of Tone mapping operators by clicking on their label (but only if they are not collapsible; if they are collapsible, then those are collapsed/expanded as before). In LightMix, the toolbar and source element labels are locked and only the layers are scrolled. Curves histogram tooltip displays "Histogram type" instead of "Histogram kind". Added label saying where to find histogram controls to Curve editor in pop out Tone mapping menu. Added missing tooltips to VFB's Auto adjustment properties. Added option to reset all curves. Region Draw in the VFB is now enabled when editing a CXR, but only when the edited CXR is of the same size as current/last rendering (matching the resolution is necessary for Resume Render, which is what the Region Draw would be for). Materials(3ds Max and Cinema 4D) Added 'Only unsupported' option to Material override to override only unsupported materials. Added mix alpha option to CoronaMix map. Added checkbox for clamping/enabling negative values. LUTs and Curves now pass channels with negative values and modify channels with nonnegative values. Collaboration(3ds Max and Cinema 4D) Image uploaded from history item keeps the item's name. Rendering(3ds Max and Cinema 4D) Added the possibility to apply Bloom&Glare on the alpha render element. This is enabled by default in new scenes, but kept disabled in old scenes. Added support of Intel Denoiser for Blackwell (NVIDIA 50-series) GPUs on Windows.. Installation Changes(3ds Max and Cinema 4D) Changed installation root (on Windows) from 'C:\Program Files\Corona' to 'C:\Program Files\Chaos\Corona'. Added dialog with Chaos account information (opened from System > About Chaos Corona/Licensing in Max, or in the Corona > About dialog in C4D). Minor changes in the UI for data usage in Preferences. Updated Cosmos service to 2025.04.04-531585 Updated Chaos License server to 6.2.1 (Cinema 4D) It is now possible to manually release interface license for Corona from About dialog. Added help links to many C4D error messages. Minor changes in the About dialog. Bug Fixes in Corona 12 Update 2Crash Fixes (3ds Max and Cinema 4D) Fixed crash when rendering with geometry motion blur enabled. (Cinema 4D) Fixed possible crash when adjusting Filter shader in Corona Sky when IR is running. Fixed crash when calling UNDO in the Corona Node Material Editor immediately after adding multiple new nodes via drag&drop. VFB Fixes(3ds Max and Cinema 4D) Fixed slowdown when Lightmix channel is shown in VFB - up to 10x slower than beauty on some PCs. Fixed highlight of checkboxes in Tone Mapping and Lightmix VFB tabs. Fixed differences in Beauty vs Lightmix render channel for complex materials. Fixed Lightmix looking different from Beauty when OCIO color management is on. Explicitly update VFB after render stamp is toggled. Fixed issue where the Lightmix context menu in the VFB was not working when right-clicking on the Lightselect names. Fixed Auto adjustment results being influenced by pixels excluded from rendering. Fixes issue where interactive rendering with Intel denoising was saved without denoising into history. Collapsing tone mapping operator type now operates independently (i.e. not opening other operators of the same type). (Cinema 4D) Fixed issue with render queue rendering in wrong color space unless VFB render was not used before. CXR layers are not added during Team Render when not needed. Materials(3ds Max and Cinema 4D) Fixed ScannedMtl triplanar mapping moving with the camera. Fix for sub-surface scattering not working on objects with decals when seen in reflections. Fixed issue where applying decal on a glass object could lead to wrong refraction in the object’s glass material. Fixed issue where NAN in Corona Color Texture would propagate further. ScannedMtl, fixed file not rendering/displaying in UI even when it is found in 3ds Max Asset Tracker. ScannedMtl, fixed "Adjust UV tiling" button being incorrectly enabled when Triplanar mapping is enabled at the same time. Fixed issue where using reflection/refraction override together with black environment could lead to incorrect results in some rare cases. Preview of Chaos Scans with triplanar mapping enabled now shows average texture color. Corona Curvature map now correctly works for objects with intersecting elements/volumes. Legacy option was added to the Curvature shader for compatibility with old scenes. Fixed issue where Corona Pattern had holes in Orthographic projection. Fixed issue where translucency settings were not considered in thin mode during conversion from V-Ray material. Added condition for use of SSS color. (3ds Max) Added legacy mode for displaying the bitmaps in OCIO as in v12 Update 1. Fixed missing lut/ies assets during rendering in case AssetManager can resolve them. (Cinema 4D) Fixed conversion of clearcoat strength and glossiness for V-Ray Scanned material. Fixed Corona bitmap with Mapping randomizer when used on material attached with non-UVW mapping. Fixed possible NaN in Scanned material. General(3ds Max and Cinema 4D) Fixed issue where Lightmix was not correctly exported to standalone. Improved the VFB refresh at the start of the production rendering. Fixed DPI scaling of licensing dialog and legal agreement dialog. Fixed wrong telemetry information link and host application name in legal agreement dialog. Fixed issue where adaptivity and denoising was incorrectly computed when using DOF solver. (3ds Max) Fixed color management warnings being displayed even when Corona is not the active renderer. Fixed missing MaxScript names for parameters in TileMap, VrScans material, CoronaCamera, Curvature map, Chaos Scatter, Corona Pattern. Fixed issue where render could be aborted when running IR and rendering bitmap in the material editor at the same time. In quiet mode (batch, command line rendering) take into account whether "Show overwrite confirmation" is enabled. If not, allow VFB history autosaving. Increase Corona Light viewport performance by not previewing hidden lights. (Cinema 4D) Fixed incorrectly loaded UV pattern mode in Chaos Scatter for scenes from saved in previous Scatter versions. Fixed UV pattern mode not showing correct default value when new Chaos Scatter is created. Fixed issues with values in Scatter lists not correctly updating for some objects when more than 8 objects were inserted. Fixed issue with Scatter lists being stored in incorrect order when document is saved immediately after deleting one of the linked nodes from the document. Fixed issue with V-Ray Sun remaining in the scene after V-Ray Sky/Dome conversion. Improvements in hair material conversion. Fixed issue with results of render queue being different for Team Render and normal render with OCIO enabled. Fixed issues with incorrect color profile and view transform when using OCIO and rendering using Team Render. Fixed incorrect material previews in Cinema 4D 2025.2.0 on Windows when using OCIO. Fixed issues with some render passes being corrupted on save when using OCIO. Fixed edge case that prevents some objects (Osds) from being visible in IR due to having a non-unique ID. Vantage Fixes(3ds Max and Cinema 4D) Fixed Vantage live link updates when deleting object after moving camera or changing sun parameter. (3ds Max) Fixed missing update of IR/LiveLink when new objects are imported into 3ds Max. Tonemapping errors are no longer shown when doing live link to Vantage. Collaboration Fixes(3ds Max) Fixed uploaded images having incorrect gamma in Gamma color management workflow.
