An enhanced retriangulation algorithm now produces improved results when creating new faces, moving vertices, or using Retriangulate on an Editable Poly object. See Editable Poly (PolygonElement).
Note: When loading a scene created in a previous version of 3ds Max into 2023.2, you can use the command
$.enableEnhancedRetriangulation = true to activate this new functionality in the base Editable Poly object.
