I have a Makehuman export in Blender (2.79) with skin mesh and cloth mesh bound to an armature. I edit the cloth mesh with Sculpt mode just fine. When I try to do the same for the skin, I enter the Sculpt mode successfully and pick tools to sculpt, but no changes are shown on the model and the model is not affected at all. However, when use ctrl + alt + z to see the history, I can see all the sculpting I've done. Why is that?
Update: when I move to Edit mode, I can see all the changes done; I can only see the changes I make in Sculpt mode, after going through edit mode. Otherwise, neither Sculpt mode or Edit mode updates the changes.
