Hey, I'm working in Zbrush, and the time has come to combine multiple subtools/objects into one subtool/object. However, the objects/subtools I'm working with all have different subdivision levels. Is combining them going to mess this up? How do I prevent this? Thanks for the help, everyone.
You should be able to reconstruct subdivs even if you lose them from merging. If you merge a mesh with 5 divisions and another with 3, you will be able to reconstruct at most 3 of the combined object's subdivisions. ZBrush won't be able to reconstruct any further if it results in triangles or ngons.
