We can assign different surface and displacement to different faces.
Setting Up Group
To add a selection of faces to a group:
- Change your selection mode to primitives.
- Select the faces in the Viewport.
- In the Viewport, hit the TAB key and select Group to add the faces to the group.
Assigning Material To Groups
Add a Material.
If you want to assign both Bxdf and displacement shader, you will need to create a collect vop to collect both surface and displacement.
Collect vop is added to H16.0.695 onward.
Assign your group to the material by setting the Material to either a collect vop (see above) or a Bxdf.
