Keep Material Boundaries

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.

Keep Textures

When on, ProOptimizer preserves texture mapping coordinates. When off, ProOptimizer removes texture coordinates. Default=off.

This option is disabled if the object doesn’t have texture coordinates.

Note: If Keep Textures is off when you optimize a mapped object, 3ds Max will display a Missing Map Coordinates dialog when you attempt to render that object.

Keep UV Boundaries

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.

Tolerance This is available only when Keep UV Boundaries is turned on. The Tolerance value controls how UV boundaries are treated. A value of 0.0 (the default), preserves all faces that have UV mapping values that differ from neighboring faces. A value of 1.0 allows any face to be removed, even if its neighbor has a different UV value.

Tip: Setting Tolerance to 0.1 preserves most mapping boundaries, but also allows a reasonable amount of optimization.
