By applying mapping coordinates to a n object, the
UVW Map modifier controls how mapped and
procedural materials appear on the surface of an
object. Mapping coordinates specify how bitmaps
are projected onto an object. The UVW coordinate
system is simi lar to the XYZ coordinate system.
The U and V axes of a bitmap correspond to the X
and Y axes. The W axis, which corresponds to the
Zaxis,isgenerallyonlyusedforproceduralmaps.
A bitmap’s coordinate system can be switched in
the Material Editor to VW or WU, in which case
