I made an OBJ file and it should look like:
But when I open it in default preview application (Mac):
It has some transparent surfaces which should be solid. I can see all surfaces when I rotate so do not know what should be changed. Face (f) items in OBJ files create a visible surface so I connected them all. Is there any specific order for the faces?
