--- title: "Supported Features" canonical: "https://documentation.chaos.com/space/VMAYA/111739052/Supported%20Features" format: markdown --- This page provides information on supported features in V-Ray for Maya based on the rendering type and hardware architecture. ## **Overview** --- These features are supported by V-Ray and V-Ray GPU in Maya. Note that IPR rendering uses Brute Force GI by default but Light Cache is also available. ## **Limitations** --- IPR Rendering does not support the particle instancer. ## **Supported Features** --- ## **Footnotes** --- **1 **– Displacement results between V-Ray and V-Ray GPU may differ slightly because of Pre-tessellation and Cache Normal settings. **2 **– Note that V-Ray GPU supports only the None and Simple Single Scatter modes for VRayFastSSS2. **3** – IPR uses Brute Force for GI by default. To use Light Cache in IPR, use the Light Cache option. **4 **– The Global max depth override can be used for Production rendering with V-Ray. IPR uses its own parameter - Trace Depth that is found in the IPR Tab of the Render Settings window. **5 **– The SimplexNoise Texture is baked on the GPU. This means that it will use more memory to render. **6 **– V-Ray Cryptomatte Render Element works only in Production rendering mode. **7 (7.1, 7.2, 7.3, 7.4, 7.5) **– 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. **8 **– V-Ray GPU does not support V-Ray Mesh Light textures. **9 **– For detailed information on the GLSL support with V-Ray GPU, see the VRayMtlGLSL page. **10 **– Fire Lights (Fire Lights) and Volume Light Cache (Smoke Color) options are not supported with V-Ray GPU. For more information, refer to their relevant pages. **11 **– Indirect Light Select modes are not supported with V-Ray GPU. **12 (12.1, 12.2) **– No GI on Other Mattes, GI surface ID and SSS Surface ID are not supported. Alpha Contribution is always rendered with a value of 1 or -1, whichever is closer to the input. GI Amount is always rendered with a value of 0. **13 **– Fog container and Affect Alpha are not supported. **14 **– V-Ray GPU supports VRayDecal with a maximum limit of 4 stacked decals, when using masks or when the translucency is lesser than 1. **15** – Currently the Lens file distortion type is not supported with V-Ray GPU. **16 **– VRaySun's Clouds require VRaySky to work. **17 **– The effect is not as strongly visible on GPU as it is on CPU. **18** – There is initial support for these render element on V-Ray GPU. **19** – The All mode of the V-Ray Profiler is not supported on V-Ray GPU. **20 **– Texture lights are not supported. VRayBlendMtl is not supported. The supported lights are: VRayLightRect, VRaySun and VRayLightSphere. **21 **– When using V-Ray Luminaire in V-Ray GPU, artifacts and errors may come up. ## **Notes** --- - GPU supports up to 16 UV sets per material. - GPU supports map channels from *0* to *15*. - GPU only supports normal maps in tangent space and world space. - In some rare cases, Adaptive Lights might produce artifacts when used with V-Ray GPU within Distributed Rendering. - V-Ray supports* .vrscenes* containing files with long names on Windows when the corresponding option is enabled in the system settings. Refer to the official [Windows documentation](https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry) for instructions on how to enable long file name support. - Currently, V-Ray for Maya supports the following Input Color Space types: - Raw - sRGB - sRGB Encoded Rec.709 (sRGB) - sRGB Encoded AP1 - sRGB Encoded P3-D65 - gamma 1.8 Rec 709 - gamma 2.2 Rec 709 - gamma 2.4 Rec 709 (video) - gamma 2.4 Encoded Rec.709g - gamma 2.2 Encoded Rec.709 - gamma 1.8 Encoded Rec.709 - gamma 2.2 Encoded AP1 - gamma 2.2 Encoded AdobeRGB - Linear Rec.709 (sRGB) - Linear P3-D65 - Linear AdobeRGB
