Recent Blender switcher here so please forgive my ignorance.
I'm trying out Blenders sculpting features. ( Very nice) But I can't seem to figure out how to do surface fall off on the brushes. eg. I have a head model and the mouth is closed, I want to use the elastic brush to seperate the lips. But the fall off means every time I try move the top lip the bottom lip moves too. In other software ( XSI and Maya) I could chose surface as the fall off method to get around this issue. Is there a similar setting in blender that I'm missing?
