		with each
		part composed of a different material. But on some occasions it may 
		be useful to have an object
		modelled as a single Mesh, yet exhibiting different
		materials.

>&#13;		Consider
		the mushroom image shown in <A
HREF="x4436.html#BSG.MAT.F.S68.601"
>Figure 35</A

		This object is a single mesh to which we need to assign two 
		materials:
		one for the stem and one for the cap. Here's how to do it.
