Hey!

I'm trying to edit some of the original creature models with ZBrush. I have no problems with importing and exporting models from and to ZBrush. My problem is that, when I edit models and model has separated parts, I manage to make holes between these parts.

Selecting WeldPoints option in ZBrush solves this problem in ZBrush, but when I export model back to 3ds max, the original rigging doesn't work anymore. I noticed that WeldPoints button reduces points number in ZBrush, but poly count stays same.

Is there some way to "Unweld points" after editing model or should I just try to avoid opening model parts?
