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.

Force Lossless Compression – When enabled, forces lossless compression for this channel when DWAA/DWAB compression is used.
