I wonder if there's a script for locking the topology of an object when you are editing so you are only allowed to do transformation operations, grab, rotate, scale, and so on, no "destructive" operations.
I use ManuelLab and Makehuman for making my models, and I accidentally change the topology, be ripping, extruding, edge looping, so I try to restore the original topology but then I encounter that the vertices indices are all messed up, and because of that if I try to join a shapekey from ManuelLab the shapekey gets corrupted.
