Chamfer updates

The following updates improve the results of chamfer operations:

• When performing a chamfer operation with the Chamfer modifier or an Editable Poly object, the Limit Effect output has been updated to prevent self intersections in chamfered surfaces. See Chamfer Modifier Reference
• Hard edges can appear on chamfer segments and cannot be corrected with the Smoothing parameter in the Chamfer modifier. The Chamfer modifier now generates improved surface normals when working with non-explicit normals, solving this problem.

Tip: You can use the command $.modifiers[N].SetVersion #VerLatest to update Chamfer modifiers that were applied in previous versions of 3ds Max, so they use the new functionality.
