Sculpting mesh problems - vertices over vertices
I'm kind of doing my own sculpting month with sculpting every day.
I use dynotopo with relative detail.
After some time especially when I try to smooth things, I get vertices that are laying above the vertices. And that makes ery ugly mistakes.
Does anyone know why this happends? What am I doing wrong or is there a way to fix this other than going into edit mode and deleting and merging them by hand?
