The following is a quote from aurick from another post:
It sounds like your groups aren’t being welded when exported from DAZ Studio. I’m sure there’s a setting there to do it, which would be the ideal solution. However, if you can’t find it there is in ZBrush in the Tool>Import menu a setting to weld overlapping points.
DAZ does, in fact, have a weld setting. But it can cause problems. I would prefer to do the weld in ZB. However, in ZB4, when I go to Tool>Import, I don’t get any menu at all, just a dialogue box that allows me to specify the location of the file to be imported. Am I missing something? Can anyone tell me how to implement the procedure described in aurick’s post?
