Edge Loop Regularizer EditPoly
Edge loop regularizer for Edit Poly. This script is an extended version of the well known edge loop regularizer script. This version has a ported part of the original script that can handle edit poly objects. The only drawback is that it can be slower when you are planning to use it on an edit poly object, because how max is handling edit poly modifiers. If you are planning to use it on an edit poly modifier, it might better to detach the part you want to regularize, and than attach it back when you finished the modification.
UPDATE: a little bug has been solved, when you run the script first on an edit poly object.
The original script has been created by Garp. I just made a slight modification on it.
