Major User-Facing Improvements
- Added possibility to render Gaussian splats using Corona Gaussian splats object.
- CoronaPhysicalMtl rewritten to Qt.
- CIE rewritten to Qt.
- Added the option to dock VFB window. Dockable option can be found in zoom menu of VFB.
- Added new Fabric material - users can control yarns, plies, fibers.
User-Facing Improvements
- VFB - Removed confirmation dialog when enabling/disabling all lightmix layers.
- Removed decimals from the (new) White Balance operator.
- Improved viewport IR text during Vantage Live link.
- Added new togglable "Collaboration" button to VFB ribbon, which shows/hides Collaboration on the left side, instead of a tab in the sidebar.
- Added option to hide/disable AI features using CHAOS_DISABLE_GEN_AI environment variable. Setting it to "1" hides:
- AI Material Generator from Cosmos
- CMasking_AiEnhancer render element
- Enhance button in VFB
- Enhance button for VFB history items
- Added new "Flip" toggle to the VFB's Zoom menu, which flips currently shown image horizontally - shortcut ctrl + /.
- Extended VFB title placeholder parameters with %cxr - this shows the path to the currently viewed cxr (VFB system settings).
- Added option for CShading_Alpha render element to include bloom & glare effect.
- Added checkbox for Corona proxy to play animation with FPS stored in the proxy file (previous behavior - default) or with the current scene FPS (similar to V-Ray proxy).
- Changed default adaptivity interval to 1. Noise level can now be estimated after 2nd pass.
- Significantly improved parsing speed, especially on CPUs with large number of threads. Geometry stage now stays consistent between renders.
- Added support for randomization by pattern to Multimap and MappingRandomizer.
- Improved the look of VFB2 tabs.
- Rewritten the UI of ColorText to Qt.
- Maps are reused and no longer duplicated when importing material from Cosmos.
- Significantly improved volume rendering when volume is lit by polygonal light sources (no environment, sun).
- Added automatic color space selection using OCIO rules when batch loading bitmaps from Corona MultiMap.
- Added possibility to drag and drop multiple selected Cosmos materials into SME. The drop position of all imports even without drag and drop has slight shift applied to it.
- Added upload conditions to the AI Enhancer button tooltip.
- When LightMix element is displayed in VFB, it is uploaded to AI Enhancer instead of Beauty.
- Added checkbox with simple triplanar mapping into CoronaBitmap.
- Improved the import of materials from Cosmos:
- Corrected the ordering of NormalTexture/MappingRandomizer/Bitmap
- Fixed 0 scaling used in triplanar texture in AI material
- Removed empty CoronaMix map plugged into SSS amount
- Triplanar, MappingRandomizer map is reused if the same map is plugged into multiple nodes
- Made UI more compact:
- top toolbar’s height decreased from 56px to 40px (VFB1 had 28px)
- tools sidebar's width decreased from 342px to 300px (VFB1 had 240px)
Bugfixes
- Fixed AI Enhancer image uploading cropped image when AI upscaling is on - now the whole image is uploaded in the original resolution.
- Fixed artifacts created by slicer caps.
- Fixed issue where IR would not update when an object with Corona Pattern modifier used option to use pattern material.
- Fixed CoronaPatternMod incorrectly setting command mode to select (e.g. when cloning using Shift + Move).
- Fixed issue where 3ds would get minimized after closing Corona Color Picker, Memory report dialog etc.
- Fixed issue where Corona Pattern Mod could crash when using RaySwitch material or Light material on it.
- Fixed "Rest" parameter in LightMix being reset when restarting rendering.
- Fixed issue with wrong gamma mapping when importing normal map from Cosmos from Corona material library collection.
- Fixed issue where triplanar mapping in Corona Scanned Material could rarely lead to NAN.
- Fixed outline material when used with camera clipping.
