The following parameters are available only when the V-Ray Material Output node is opened in the V-Ray Material Builder.

Texture and Mapping

Show Texture – This option is enabled by default. It allows any attached textures to be visible in the viewport. 

UV Attribute – The name of the UV attribute that Houdini uses to show the texture in the viewport. 

Texture Path – The node path of the texture as relative reference should be entered here in order for the V-Ray ViewportTex SOP to be used. This way all UV changes attached in the imagefile node are visible in the viewport.

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.

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 metallness 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 metallness must be referred to this parameter in order to be rendered correctly in Houdini's vewport.

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.
