Hello Blender Community,
I imported an OBJ mesh into Blender. When I set the shading to smooth some edges appear sharp and others don't, though I haven't added the edge split modifier.
If I go into Edit Mode I can see the blue lines indicating the sharp lines. I already checked if there are doubles by merging vertexes by distance and I checked if the normals are all pointing in the right direction. Does anybody know what happened here?
