EdgeSmooth is a free, open source plugin that makes smoothing in 3dsmax a lot easier. It allows you to smooth an editable poly by setting edges to "hard" or "soft". A "hard edge" means that the faces using the edge share no smoothing groups, a "soft edge" is the opposite. This will probably feel familiar to Maya users!
-The plugin uses smoothing groups, so you can mix it with using traditional smoothing. It may however change the smoothing groups on all faces in the object!
-EdgeSmooth only works with Editable Poly objects, not with the Edit Poly modifier.
