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 connect to the collect_output both the surface and displacement shaders inside a PxrMaterialBuilder node. 

Assign your group to the material by setting the Material to either a collect vop (see above) or a Bxdf.
