Controls how ProOptimizer treats objects with materials or texture mapping.
When on, ProOptimizer preserves boundaries between materials. Points that belong to faces that have different materials are frozen, and not removed during optimization. Default=on.
When off, ProOptimizer can remove faces along the boundary between materials.

This control is available only when Keep Textures is turned on. When on, ProOptimizer preserves boundaries between UV mapping values. When off, ProOptimizer disregards UV mapping values. Default=off.
