I know that there is an Edge Split modifier, but it actually splits geometry edges, which causes problems with further modeling. When I use "Shading: Smooth" and then enable Auto Smooth, it works nice, with adjustable smooth angle. But when I export my model as .fbx, it doesn't export these smoothing groups (after exporting, model looks like it has totally "Smooth" shading) Do I have to somehow 'apply' Auto Smooth before exporting? I've tried applying Visual Transform, but it didn't helped.
Edit: Exporting as .obj gives the same results, so it's not .fbx export fault.
