I've having fun doing morph targets in Blender but I was wondering. Is there a way to isolate vertices so they are not affected when you are sculpting. For instance, I want to create a fat belly morph so I use the inflate tool but it also inflates the vertices of the belly button as well. Is there a way to where I can isolate the vertices of the belly button so they remain unaffected by the inflate tool so the belly button still retains a normal look rather than a squished in or puckered look? Thanks in advance.
