Footnotes
1 – RT rendering supports motion blurred frames on integer numbers only. For example, starting the render from frame 1 produces correct motion blur, but starting from frame 1.25, will produce incorrect motion blur.
2 – Displacement results between CPU and GPU rendering may differ slightly because of Pre-tessellation and Cache Normal settings.
3 – Using Light Cache (as a secondary GI engine) with V-Ray RT is possible only when V-Ray RT is set as Production render, or with From file mode (already computed Light Cache .vrlmap) when using ActiveShade.
4 – Irradiance Map is supported (only from file).
5 – Displacement can be enabled or disabled for V-Ray RT only in ActiveShade Mode, but not in Production Rendering Mode.
6 – In normal mode, the Light Select pass contains GI information only in RT GPU. The Raw mode is not supported in RT GPU.
7 – The Sampler Info Render Element supports different UVW Coordinate types through its different pass types. For more details, please see the Sampler Info Render Element page.
8 – When rendering with V-Ray RT CUDA, the VRayShadows Render Element is incompatible with Adaptive Lights and may render incorrectly if used together.
9 – Starting with V-Ray 3.6, the VRayColor2Bump texture will no longer be needed for procedural textures in order to be supported by V-Ray RT GPU. For earlier releases, all procedural textures are supported by RT GPU when used for Bump mapping through a VRayColor2Bump texture attached to the Bump slot.
10 – These plug-ins are only partially supported by V-Ray RT GPU.
11 – The Color feature of VRayEdgesTex is not yet available in V-Ray RT when the engine type is set to CUDA. However, the Rounded Corners feature is fully supported.
12 – The texture is baked for rendering on the GPU. This means that it will use more memory to render, than a fully supported procedural texture.
13 – BerconTile is not supported in RT CPU.
14 – RT GPU always uses raytraced multiple scattering. It does not support raytraced (solid) and raytraced (refractive) settings.
15 – The Skylight portals in RT GPU work only in Simple mode.
Additional Notes
-
RT GPU supports map channels from 0 to 15.
-
RT GPU only supports normal maps in tangent space.
