I am trying to bust up a mesh so that I can apply different levels of subsurfacing to different parts. I think that this is the best/only way to do this,;let me know if I am wrong.
At any rate, I cannot seem to designate a group of verticies as belonging to a new object. I have used the Y key, which does allow a clean separation , but the separated items remain part of the same mesh. Is there some other way I should approach this, or is there something I am missing to finish the job on splitting.
If you want to keep clean edges which will match back up after separation, extrude the edge verts of each piece, but don’t move them.
The subsurf will no longer round your pieces but will keep nice clean edges for you right up to the mesh edge. This will work for different pieces with different subsurf levels applied.
Edit- sorry Stefano, I’m sure you know this already. - Edit
