Convert a Mesh Selection to a different Type (eg Vertices to Triangles, etc)Bydefault, Vertices map to Triangle one-rings, and Triangles to all contained vertices. If bAllowPartialInclusion is disabled, then more restrictive conversions are performed, as follows: For To-Vertices, only include vertices where all one-ring triangles are included in FromSelection. For To-Triangles, only include triangles where all tri vertices are included in FromSelection. For To-PolyGroups, only include groups where all group triangles are included in FromSelection
