Hi! I've encountered a problem with normals on one imported model. It has like "glued polygons" which causes some artefacts. I tried applying normals, reverting them, connecting and welding, but nothing helps. Also i tried to set normals manually but it doesn't look good no matter what I do. Deleting all the tags including phong doesn't do anything as well... Is there a way to fix it or it's just what model is like?
