New features in latest...

[Luma3d]

version of Vray. I've been seeing users talk about how great the new gpu engine has been. What new features have been added? Is it mostly performance?

Hi, thanks for posting.

What new features have been added?

What period do you refer to? Here are all the updates in a list - https://docs.chaos.com/display/VMAX/...ng-NewFeatures

New features V-Ray GPU (from the link above):

V-Ray GPU

• VRayEnmesh GPU support
• V-Ray GPU bitmaps caching when rendering animations
• Multiply by opacity for VRayLightMtl in V-Ray GPU
• Support for 3Ds Max Standard light projection map on GPU
• Add support for MultiMatte Render Element on V-Ray GPU grid volume shader
• Add support for VRayCryptomatte Render Element on V-Ray GPU grid volume shader

Modified features:

V-Ray, V-Ray GPU

• Add separate control for IPR Ray Bundle Size in GPU UI
• Implement edge trimming into the core for V-Ray Standalone and V-Ray GPU
• Export Color Correction settings from Forest Pro Material rollout
• Abort on missing OCIO display corrections
• VRayUVWRandomizer Flip UVs option
• Support for rendering Particle colors based on different channels

V-Ray GPU

• Improved bump mapping for small objects
• Volumetric scattering with anisotropic phase function

Bug fixes:

V-Ray GPU

• VRayEnmesh "Use mesh UVW mapping" does not consider source object's mapping channel different than 1 on V-Ray GPU
• Crash on starting IPR with GPU, DR on and VRayCryptomatte RE with ID type set as Node Material Name or Node User Property
• Aborting rendering while Uploading Bitmaps is not responsive
• Garbage data read when there is displacement in a scene
• Crash when scenes containing Image sequences and V-Ray Sky are rendered with CUDA and then RTX engine
• Assert and NaNs in the result when reading diffuse light select values from light cache
• Fix reading uninitialized memory on the first iteration of LC/K3
• Select object and Pick object material functionality in VFB is broken with V-Ray GPU IPR
• Render freeze when rendering animated object with RTX, motion blur and V-Ray Denoiser
• GPU Light cache freeze when rendering animation with a specific scene on a machine with multiple gpu devices
• Phoenix Particle Shader in Point mode randomly disappears on a test scene with OptiX
• Print a warning for CUDA 12 min driver version
• Emissive material does not appear in VRaySelfIllumination behind refractive object
• VRaySphere is not rendered with RTX
• Rendering stucks when using the Bucket image sampler and Textured render mask
• MultiMatte does not consider material IDs nested in VRayBlendMtl with blend amount
• Regression of spot/direct lights intensity
• evalSamplerTex might return uninitilized .w in some modes
• Instanced objects render black when "Cast shadows" is unchecked and Edge trimming in Chaos Scatter is active
• Parsing version 470.161.03 failed
• VRayClipper does not have correct material IDs when rendering with V-Ray GPU
• Cryptomatte render element doesn't work for objects behind glass
• Bump mapping doesn't work correctly on a plane
• MultiMatte does not work with material IDs within VRayBlendMtl
• MultiMatteID is not propagated through nested materials
• VRayVolumeGrid and Smoke renders artefacts with GPU

Nice...how much of this crosses over to Vantage?
