Short description of error
Polys get wrong normals when extruded. There seems to be no exact order for this to happen. Sometimes it works fine. Sometimes is so bad that half of the polys are right half are wrong. Using align normals does not fix the issue. It seems to align them opposite of the camera view or object exterior so to speak. Other times it keeps some in one direction, others in opposite direction, just flips them around.
Exact steps for others to reproduce the error
- Make a plane from top view
- Delete 1 vertice
- Extrude on z-azis but cancel movement. Move extruded selection around and you will see that normals are in wrong direction(or try until buf occurs).
