Ok I have ran into an issue with mesh generation. It doesn't seem like it creates clean meshes. A common issue is that some vertices are pulled in inside other edges, creating overlapping edges/polygons. This creates very sharp, harsh lines when I am cleaning up the texture in 3dcoat. Most of the time I have to go in manually and locate each one of these in a 3d editor (currently Wings) and pull them out. This can be really painful with big objects.
What is causing these kind of artifacts in the mesh generation, and is there any workaround for it, other than cleaning up every case where it happens? It can happen even on fairly flat surfaces.
