Overview


The VRayRenderElement node allows the user to add different render elements to the render output that can be later used for compositing. To use the VRayRenderElement node, connect it to the Scene node and pick the render element you want from the drop down menu.

Render Element Types


When creating a VRayRenderElement node, a prompt allows users to specify which render element to create.


Layer name – Specify the name for the render element that will show up in the channels list. 

 

The following render elements can be created:

Render Element NameCategoryDescription
Atmospheric EffectsBeautyAtmospheric effects such as VRayEnvironmentFog.
BackgroundBeautyImage background, such as any background textures specified using the Environment Settings | VRayBackground.
Bump NormalsGeometryNormals generated by bump maps from the camera view.
CausticsBeautyThe caustics of the material. These caustics are present only when the Caustics option is enabled. This channel does not include GI caustics.
CoverageUtilityFor each pixel, the final values for the render element are taken from the object that makes the largest contribution to that pixel.
CryptomatteMatteUses the Cryptomatte convention by Psypop to encode mattes into multichannel OpenEXRs
DiffuseBeautyPure diffuse surface color.
DenoiserUtilityUsed to apply a denoising operation to an existing render after the image is completely rendered out.
ExtraTexUtilityRenders the entire scene with one texture mapped on all objects.
GIBeautyThe diffuse surface global illumination. Only present if Global illumination is enabled.
GI RawBeautyRaw diffuse global illumination (not multiplied by the diffuse surface color). Only present if Global illumination is enabled.
Light SelectBeautyExtracts the contribution of a light or a set of lights to the scene to a separate render element.
LightingBeautyDiffuse direct surface lighting.
Light RawBeautyRaw diffuse direct illumination before it's multiplied by the diffuse surface color.
Light TotalBeautyTotal lighting in the scene, both direct and indirect.
Light Raw TotalBeautySum of all raw lighting, both direct and indirect.
Matte ShadowBeautyMatte shadow part of the image.
Multi MatteMatteCreates selection masks based on an object ID or material ID.
NormalsGeometrySurface normals in camera space.
Object IDMatteObject ID (set through the VRayObjProp node).
ReflectionBeautyReflections on the surface.
Reflection RawBeautyPure surface reflection before it is multiplied by the reflection filter color.
Reflection FilterBeautyReflection filter (the color by which the raw reflections are multiplied to give the final surface reflection). This can be considered an alpha channel for reflections.
Reflection GlossinessBeautyReturns a float value that corresponds with the Reflection Glossiness value of an object's material.
Reflection Highlight GlossinessBeautyReturns a float value that corresponds with the Highlight Glossiness value of an object's material.
RefractionBeautyRefractions of a surface.
Refraction RawBeautyPure surface refraction before it is multiplied by the refraction filter color.
Refraction FilterBeautyThe refraction filter mitigates the raw refraction layer. This render element returns the color by which the raw refractions are multiplied to give the final surface refraction. This can be considered an alpha channel for refractions.
Refraction GlossinessBeautyReturns a float value that corresponds to the Refraction Glossiness value of an object's material.
Render IDMatteNode render ID of the object that contributes most to the pixel value.
SSSBeautyRenders just the subsurface part of the VRaySSS2 material on a separate layer.
Sample RateUtilityDisplays the work being done on the image as it is rendering, and will show the job done when the render completes.
Self IllumBeautySelf-illumination of the surface.
ShadowBeautyDiffuse light blocked by other objects.
Shadow RawBeautyRaw light blocked by other objects.
SpecularBeautySurface specular highlights.
VelocityGeometrySurface velocity of an object. This render element is useful for generating motion blur in post-production.
ZDepthGeometryZ-depth of the surface.

Parameters


 

 

 

Channel – Specifies the channel to store the render element.

Additional parameters become available depending on the current render element. See the individual render element pages for additional information.
