virtual bool RequiresInitialVtxNormals&40;&41; const
Remarks
Optional base mesh per-vertex normals. Default enabled. These are computed at Tool startup if required, and then not modified, so can be passed to multithreaded operators/etc If this function returns true, BaseNormals will be initialized in Tool Setup(). This has some cost and should be disabled if not necessary.
