To assign materials to specific faces on a ProBuilder mesh, you can use explicit face indices or semantic face directions like "up" or "side" to apply different materials in a single operation. The mesh is then automatically rebuilt and refreshed within the Unity Editor.

Yes, you can apply different materials to the top and sides of a ProBuilderMesh automatically by using the semantic face direction feature, such as assigning a grass material to the top faces and dirt to the sides without manual adjustment.

The best way to create a multi-material ProBuilder mesh without manual face selection is by targeting faces through semantic directions or explicit indices, which rebuilds the mesh and applies the specified materials efficiently in one operation.

No, this material assignment tool does not work outside the Unity Editor during gameplay. It is specifically designed for use within the Unity Editor during mesh modification workflows to rebuild and refresh the ProBuilderMesh.

To assign a material to ProBuilder faces using a specific direction, use the command syntax with faceDirection and material parameters, such as faceDirection="up" material="Grass.mat", which applies the material to the top faces and rebuilds the mesh.

Manually assigning materials to ProBuilder mesh faces takes time because you must select each face individually, whereas using a semantic direction or explicit face index approach applies materials to multiple specific faces in a single automated operation.
