Hello everyone,

V-Ray 7 for Cinema 4D Update 4 is out.
The builds can be downloaded from the Downloads section on our site.

Here is the change log for release version 7.40.00

New features

  • Introduce V-Ray Quick Sun caustics solver
  • Add support for using AMD Graphics cards with V-Ray GPU
  • Ability to relight Gaussian splats using scene lights
  • Introduce Chaos Vantage rendering inside the Cinema 4D Viewport
  • Introduce Light Cache denoising
  • Added Foreground and Background folders in the fixed stack of Layers in VFB to prevent issues with Lens effects when using an image for Background
  • Improved Background layer called Image layer
  • Add Histogram in VFB

Modified features

  • Add out of frustum displacement quality control
  • 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
  • Speedup bitmap loading by deferring color corrections to the GPU on bitmap access
  • Add OSL/GLSL/MDL support for the Metal V-Ray GPU engine on macOS
  • Write Z-depth render channel for Gaussian splats
  • Improve loading bitmaps on multiple GPUs
  • Minor performance improvement to Cryptomatte layer performance
  • LightMix can produce negative pixels with values very close to 0
  • Avoid the max samples level GPU warning during interactive rendering
  • Improve time zones supported by the night sky
  • Improve VFB Layers performance

Bug fixes

  • Wrong buckets from local machine with DR render in scene with changing camera objects and camera type overrides
  • 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
  • Gaussian splats produce artefacts when the splat is behind object with opacity on GPU
  • VRayGaussianGeom clipping mask with procedural texture in Object XYZ space doesn’t match CPU
  • Artefacts in VRayZDepth with gaussian splat behind object with opacity
  • TexBitmap with UVWGenProjection is invalid as bump map on GPU
  • Stars brightness in Night Sky affect Clouds differently in V-Ray GPU
  • Wrong results with affect matte surfaces for VRayGaussianGeom and certain camera angle
  • Differences between CPU and GPU render results for a translucent/refractive VRayMtl with Coat darkening
  • OpenPBR 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 randomly while rendering a specific scene
  • TX Textures stop the rendering process
  • Moon is distorted when Horizon offset is used
  • Different position on VRaySun disk with Horizon offset parameter on CPU and GPU
  • VRayUserScalar and VRayMultiSubTex do not render correctly when using GPU
  • TexFloatOp crashes with V-Ray GPU
  • Some deep samples in Z-Depth merge mode have alpha less than 1.0 causing artifacts with compositing
