yeah, Blender has some of these tricky tricks, hopefully we got a better performance with the new opengl 2.1 support and opensubd btw, are you sculpting in dyntopo mode or multiresolution? actually blender has no deep history stack like maya or softimage, because there are modifier and data properties to keep important…
Someone can tell me how to set proper smooth groups in Blender so I can export them? I tried to use "Mark sharp" method, and every time I open this file in Marmoset Toolbag 2 looks like 1 smooth group ... Damn ... I wish Blender had smooth group like 3DS Max.
