Page History
This page provides details on how to create and edit USD material primitives from V-Ray VOP nodes within Material Library LOP.
For details on how to work with MaterialX materials, refer to the MaterialX Support page.
Create and Assign Materials
With V-Ray and Solaris you can create Material VOP nodes that are translated into USD materials.

To create a global Extra Texture AOV, add a V-Ray ExtraTexAOV VOP in a shading network inside a Material Library VOP, and point a RenderVar LOP to the Extra Bind Name parameter value of the VOP node.

Override Materials
To override V-Ray materials in Solaris, use either the Edit Material Properties LOP or right-click on the material property in the Geometry Spreadsheet and select Edit Property to modify it.
You can also override non-V-Ray materials through the Edit Material Network LOP. This node fetches the material network and allows you to alternate whatever you want inside it.
More detailed instructions on overriding materials are available at Material Override.
LPE Labels for Materials
Light Path Expressions (LPEs) are a special type of render element. They use regular expression patterns to record selected events of light contribution along the path of a ray. LPEs can be modified to render information for only specific materials by adding an LPE label.
LPE labels are added to materials through the V-Ray MaterialID material, which is added between the material and the output nodes. The label can take numeric or text values and when used in an expression it needs to be preceded by m and placed inside single quotes. See the Advanced Light Path Expressions page for more information on how to work with LPE labels.
