...

Section

This workflow applies to Houdini only.

1. Go to V-Ray Renderer ROP > Objects tab > Material Overrides tab.

2. Enable Material Overrides and add a new override using the + button.

3. Under the Objects parameter, select an object to apply the override material to.

  • This can be a single object, e.g. “/obj/object_A”
  • This can be a set of objects, e.g. “/obj/object_A /obj/object_B”
  • This can be a pattern, e.g. “*” for all objects in the scene
  • This can be an isolated pattern, e.g. “*_A” → this only selects object_A

4. Select the Material to use for overriding.

Optional: Enable the Use Displacement from Override Material option to override the displacement/subdivision settings for the selected objects. If the override material has a Displacement VOP inside, it is used. If such a VOP is not present, no displacement is applied to the selected Override For objects.

5. Render. Now the selected material should be used for the selected objects.
