The Optimization Options rollout lets you control how ProOptimizer treats such features as object borders, materials and mapping, vertex colors, and sub-object selections.
Controls how ProOptimizer treats object borders.
Controls how ProOptimizer treats objects with materials or texture mapping.
Controls how ProOptimizer treats objects that have vertex colors assigned to them.
The Normals group lets you manage the face normals of the geometry you are optimizing.
Each of the Merge tools adds a preprocessing step to the optimization process. These can help correct specific problems in a model.
These options control how ProOptimizer treats vertex sub-object selections. You can’t create a sub-object selection in ProOptimizer, but it can acquire a vertex selection from an object or modifier below it on the stack.
