Description
MultiMatte

N/ACreates selection masks based on object G-buffer ID or material ID.

VRayAlpha

2

Alpha transparency

VRayAtmosphere

2

Atmospheric effects

VRayBackground

2

The image background
VRayBumpNormalsThe normals generated by bump maps, in screen space (which is not the same as camera space). Use the VRaySamplerInfo render element to get the normals in camera, world or object space.

VRayCaustics

1

2

The caustics on the material. Only present when the Caustics option option of V-Ray is enabled. This channel does not include GI caustics.
VRayCryptomatteUses the Cryptomatte convention by Psypop to encode mattes into multichannel OpenEXRs.
VRayDenoiser 4Applies a denoising operation to the image after it is rendered (with the neccessary channels).
VRayDiffuseFilter

2

The pure diffuse surface color. Note that this is different from the standard 3ds Max Diffuse render element, which contains the diffuse surface lighting.
VRayDRBucketN/AN/AN/AN/AShows which render node rendered which bucket during distributed rendering
VRayExtraTexN/AN/AN/ARenders the entire scene with one texture mapped on all objects.
VRayGlobalIllumination1 2The diffuse surface global illumination. Only present if Global illumination is enabled.

VRayLighting

2

The diffuse direct surface lighting.
VRayLightingAnalysisProvides visual representation of the lighting intensity within a rendered frame.
VRayLightSelectExtracts the contribution of a user-defined light or a set of lights in the scene as a separate render element.
VRayMatteShadowThe matte shadow part of the image.
VRayMtlID

3

The material ID of the object.
VRayMtlReflectGlossinessGrayscale image from materials' reflection glossiness amount.
VRayMtlReflectHilightGlossinessGrayscale image from materials' highlight glossiness amount.
VRayMtlReflectIORN/AGrayscale float image from materials' Fresnel reflections IOR amount.
VRayMtlRefractGlossinessGrayscale image from materials' refraction glossiness amount.

VRayMtlSelect

This element allows you to write the result of a V-Ray compatible material into a separate element. The material can be a top-level material or a sub-material of VRayMtlBlend.
VRayNoiseLevelOutputs the noise level for pixels. Same as the noiseLevel render element produced by the VRayDenoiser, but as a standalone render element.
VRayNormals

The surface normals in screen space (which is not the same as camera space). To output the normals in camera/object/world space, use VRaySamplerInfo render element.

VRayObjectID

3

The object G-buffer ID (set through the node's Properties dialogue).
VRayObjectSelectStores only the object(s) called out with a specific Object or Material ID.
VRayOptionREN/AN/AN/AN/AControls some internal settings for V-Ray that are otherwise inaccessible.
VRayRawDiffuseFilterA solid mask of raw diffuse surface color information not affected by fresnel falloff.
VRayRawGlobalIllumination

2The raw diffuse global illumination (not multiplied by the diffuse surface color). Only present if Global illumination is enabled.

VRayRawLighting

2

The raw diffuse direct illumination before it's multiplied by the diffuse surface color.
VRayRawReflection

2

The pure surface reflection, before it is multiplied by the reflection filter color.
VRayRawReflectionFilterN/AA solid mask of raw reflection information not affected by fresnel falloff.

VRayRawRefraction

2

The pure surface refraction before it is multiplied by the refraction filter color.
VRayRawRefractionFilterN/AA solid mask of raw refraction information not affected by fresnel falloff.
VRayRawShadow 2The raw light that was blocked by other objects.
VRayRawTotalLightingThe sum of all raw lighting - direct and indirect.
VRayReflection 2The reflections on the surface.
VRayReflectionFilter

2The reflection filter (the color by which the raw reflections are multiplied to give the final surface reflection). This may be considered as an alpha channel for the reflections.
VRayRefraction 2

The refractions on the surface.
VRayRefractionFilter 2The refraction filter (the color by which the raw refractions are multiplied to give the final surface refraction). This may be considered as an alpha channel for the refractions.
VRayRenderID 3The node render ID of the object that contributes most to the pixel value.
VRayRenderTime
Shows a floating-point number for each pixel's render time measured in milliseconds.
VRaySampleRateN/AN/AN/AN/AShows an image where the pixel brightness is directly proportional to the number of samples taken at this pixel.
VRaySamplerInfoN/AN/AN/AN/AProvides information about various aspects of the shaded points - position, normal, bump normal, reflection/refraction vectors and UVW coordinates. Can be used f.e. for world position passes or normal passes.
VRaySelfIllumination

2

The self-illumination of the surface.
VRayShadows 2The diffuse light that was blocked by other objects.
VRaySpecular 2The surface specular highlights.
VRaySSS2Renders just the subsurface part of VRaySSS2 and VRaySkinMtl materials on a separate layer.
VRayToon 3Stores the toon outlines information.
VRayTotalLightingThe total lighting in the scene, direct and indirect.
VRayUnclampedColor 2The unclamped image color.
VRayVelocityThe surface velocity. This channel will not be generated if 3d motion blur is enabled.
VRayWireColorThe wire color of the object as set in the 3ds Max scene. This can be used to generate masks for the objects based on their wire color.
VRayZDepthThe z-depth of the surface.
