Replacing a subtool with an updated version

[system]

Is it possible to replace a subtool with a newer version of the same in the same place as the old one? For example if I have a big character with several subtools and I realised I needed to fix his helmet in my regular 3D program (Blender) how would I go about replacing the old subtool helmet with the new one?

I’ve seen some people suggest that one should just export the objs and re-import them but then I’d lose my subdiv levels so I’m looking for a better solution than that.

You can use GoZ to import the subtool into a 3D app and fix it then it will re-import it back into Zbrush. If you change the topology you’ll have two options. One is to throw away the subDs and one is to reproject the subDs. Reprojecting the subDs should let you keep your divisions and keep your new edits.
