## **Modified Features**

---

**V-Ray**

- Add submenu option for Material AI Generator in Chaos Cosmos menu
- Import animated parameters of materials and objects
- Add support for Scatter Clustering
- Minor performance optimization for 2D displacement


**V-Ray GPU**

- Speedup bitmap loading by deferring color corrections to the GPU on bitmap access
- Add OSL/GLSL/MDL support for Metal
- Write Z-depth render channel for Gaussian splats
- Improve loading bitmaps on multiple GPUs
- Avoid the max samples level GPU warning during interactive rendering


**V-Ray VFB**

- Minor performance improvement to Cryptomatte layer performance
- LightMix can produce negative pixels with values very close to 0
- Improve VFB Layers performance


**VRaySun**

- Improve time zones supported by the night sky


## **Bug Fixes**

---

**V-Ray**

- TexTiles, TexStucco and TexSplat are flipped with V-Ray GPU when using an input texture
- Normal maps are imported in the wrong order from Cosmos when using Triplanar mapping
- Cryptomatte write metadata parameter has no default value
- Disabling the displacement from the Overrides tab doesn't work


**V-Ray GPU**

- Gaussian splats produce artifacts when the splat is behind object with opacity on GPU
- VRayGaussianGeom clipping mask with procedural texture in Object XYZ space doesn't match CPU
- Artifacts in VRayZDepth with the gaussian splat behind the object with opacity
- TexBitmap with UVWGenProjection is invalid as a bump map on the GPU
- The stars' brightness in Night Sky affect Clouds differently in V-Ray GPU
- Wrong results with affect matte surfaces for VRayGaussianGeom and certain camera angles
- Differences between CPU and GPU render results for a translucent/refractive VRayMtl with Coat darkening
- OpenPBR is missing Sheen/Fuzz on Metal
- Caustics intensity in V-Ray GPU doesn't match CPU
- Wrong lighting with resumable rendering if the rendering is paused during Light Cache Calculations - V-Ray GPU - RTX and CUDA
- Light's intensity multiplier does not work with textures and directionality set to 1
- Motion blur's Bias parameter is not taken into account
- Cinema crashes while rendering a specific scene
- TX Textures stop the rendering process


**Distributed Rendering**

- Wrong buckets from local machine with DR render in scene with changing camera objects and camera type overrides


**VRaySun, V-Ray GPU**

- Moon is distorted when Horizon offset is used
- Different position on VRaySun disk with Horizon offset parameter on CPU and GPU


**VRayTextures**

- VRayUserScalar and VRayMultiSubTex do not render correctly when using GPU
- TexFloatOp crashes with VRay GPU


**Deep Output**

- Some deep samples in Z-Depth merge mode have alpha less than 1.0 causing artifacts with compositing
