The problematic edges are small, convex, sharp protrusions on a larger concave, smooth surface. Edge split, smooth, and subdivision modifiers do not achieve the smooth surface I'm looking for. Is there a way to force edges with larger than, say 290 degrees to become less obtuse? Note that I describe the edge this way because that is the side of the surface I'll be viewing (not side of the surface with the equivalent acute angle). Here's an example:
The mostly horizontal lines are where thin, jagged protrude out of the otherwise smooth surface. Close-up:
Using the Smooth brush in sculpt mode with dynamic topology and Collapse short edge enabled gives (applied on various scales for demonstration):
This is close but is there a way to now make the 'crumpled'-looking surface become more like the other smooth surface?
