Painting Selected Faces

Use a multi/sub-object material to control the location of your painting. A multi/sub-object material is simply a container for multiple sub-materials assigned to different faces of the same object.

Any sub-material can have a combustion map, so you can use combustion to affect only the selected faces.

To paint selected faces:

1. In 3ds max, select the object you want to paint.
2. In the Modify panel, apply an Edit Mesh modifier to the object.

Note: If you are working with an editable mesh object, or a patch or NURBS surface, skip step 2. For geometry primitives, an option is to convert the object to a mesh, patch, or NURBS surface before step 3. However, you then lose the ability to adjust object parameters (for example, the radius of a sphere, the height of a box).

3. Enable the Face sub-object as the selection level. Select the faces on which you want to paint.



4. Drag a material from a sample slot in the Material Editor onto the selected faces.
5. Disable the Face sub-object.
6. In the Material Editor, click Pick Material from Object and pick the material from the geometry.

You now have a new multi/sub-object material. The original material appears as a sub-material applied to the selected faces.



7. In the multi/sub-object material, find the material assigned to the faces you want to paint. Click the material's name to edit the sub-material.
8. Assign a combustion map to the Diffuse component of the sub-material applied to the selected faces.
9. Click Edit to launch combustion.
10. Use the tools in combustion to modify the material.
