I keep getting this error when I try to add more detail to a mesh I edited in Meshmixer. I've tried reducing the poly count and remeshing it. I've tried retrangulating it in Wings and Mesh lab, but I still get the same error. I've fixed this before by cleaning up a mesh in meshmixer and then exporting it, but for some reason I can't find the effected area easily and mech lab isn't finding it for me either.
Any help would be greatly appreciated. I have the orignal, but I did a lot of tweaking that I don't want to loose, so if I can keep the meshmixer edits that would be great.
