how to use curvature in paint mode? i'm trying to use curvature while painting texture, but it seems to fail in some way.



dirty vertex color seems fail too



i just modeled this object in one minute in freshly opened blender. what am i supposed to do to make right curvature calculations?

more simplier shape just appears to have no cavity at all.



i'm using blender 2.76b btw

EDIT:
just tested it with deformed plane and it worked!!!



but how am i supposed to paint over complex mesh?
come to a solution based on the fact that cavity is calculated in blender based on the verticies. made a tripple subdivisio and was able to paint edges properly.
