StickUVW

Description

If a texture projection operator is reading from somewhere above the Modeling region, StickUVW changes the texture projection operator to read from the top of the Modeling stack (so that UVs are computed after modeling deforms but before shape animation or enveloping). Textures using these coordinates will appear to stick as the object is deformed by shape animation or enveloping.

StickUVW takes a list of objects and UV properties (texture projections) as input. If an object is a primitive, such as a mesh or a NURBS surface, the command changes the current UV properties used by the materials (see Material.CurrentUV) assigned to the object. If a texture projection does not have an operator (because the operator was frozen), the command has no effect.
