This page provides information about the V-Ray Material Output node in V-Ray for Houdini.
Overview
The V-Ray Material Output node collects various shader nodes. It gives you control over which shader goes in the render output.

Node
The vrayMaterialOutput node offers only input slots for the Material, Surface or Simulation shader. There are no output slots in this node.
Parameters
The Arbitrary Output Variable (AOV) implementation utilizes a V-Ray Extra Texture render element. The AOV will be populated only by those objects in the scene which share the same material assignment. Multiple Material Output VOPs can write to the same AOV when the Name parameter is the same between them – in such cases the final image will be an Additive composite of the individual elements.
AOVs – Specifies the number of AOVs to export.
Name – Specifies the AOV name. When multiple Material Output VOPs write to the same AOV, the results are composited in Additive mode.
Color – Default color when no input connection is present.
Force 32-bit Output – When enabled, stores the Extra Texture render element as a 32-bit float even when writing a 16-bit raw image. This option applies only to multichannel .exr files.
Force Lossless Compression – When enabled, forces lossless compression for this channel when DWAA/DWAB compression is used.
Viewport Shading
UV Set Name – Specifies the UV Set Name.
Diffuse Texture – Selects a diffuse texture from a list of all available textures within the V-Ray Material Builder. The list contains only ImageFile textures.
Opacity Texture – Selects an opacity texture from a list of all available textures within the V-Ray Material Builder. The list contains only ImageFile textures.
Reflection Texture – Selects a reflection texture from a list of all available textures within the V-Ray Material Builder. The list contains only ImageFile textures.
Metalness – The metalness of the default V-Ray Material node inside the V-Ray Material Builder. If a new V-Ray Material is created within the V-Ray Material Builder, its metalness must be referred to this parameter in order to be rendered correctly in Houdini's viewport.
Roughness – The roughness of the default V-Ray Material node inside the V-Ray Material Builder. If a new V-Ray Material is created within the V-Ray Material Builder, its roughness must be referred to this parameter in order to be rendered correctly in Houdini's viewport.
Enable – Enables displacement.
Displacement Texture – Controls how the displacement looks in the Houdini's viewport.
Scale – Controls the displacement scale.
Offset – Controls the displacement offset.
Method – Specifies the displacement method.
Vector Space – Specifies the vector space from UV Tangent, Object Space, and World Space.
Up Vector – Specifies the UV Vector.
