LA Dodgers Logo Extrude problem
I made this LA Dodgers logo in illustrator. When I bring this text into cinema 4d everything is okay but when I extrude the nurbs it creates extra polygons & isn’t flat once extruded. Is there a way to clean up these extra polygons or prevent this surface distortion once extruded?
