Before managing materials, you need to know some basic concepts about
materials.
More information about applying materials and the Material
Palette can be found in the Material Definition User's Guide.
Important:
When a material is not in session, as is the case in the
Shading with Edges mode, the name of the Apply
Materials node in the tree contains a stored alias of the material
name that is linked by the Apply command. In rare
circumstances, this alias can be inconsistent with the actual linked material name.
For example, if the name was changed without using the Apply
command while the material was in session. This scenario will not occur when a
material is in session.
