Thanx for the reply. I would think it was the mesh only it seems to a happen to a random subtool, and randomly too. It even happens to subtools I have transposed several times. On the 5th time it will give me the error. It will happen on visible subtools I haven’t even moved. It just makes no sense. But is very frustrating. Zbrush has a-lot of bugs. It seems I’m here posting a couple times per week on things that are mostly unsolvable. I keep having to find work-arounds.
Also there is another weird thing. Sometimes when I Tpose my mesh subtools that have their visibility turned off will turn themselves on and be tposed. This is annoying because some of my tools are highpoly and I cant do my tpose with the high poly subtools turned on. However, When this happens the subtool that turned itself on often is the one that gives me the “changed, and re-import” error.
