Hey guys!

Following Grenade tutiorial I approached the moment, where Tim made Smoothing groups from UV shells (using TexTools). So, the question is- why should I do it?

Hey there :)

Well I must admit that I don't know about the very in-depth reason why you should do that far as what I learned you simply need them in order to make your normals bake fine.
Without these smoothing groups, chances are that you get undesired hard edges OR smoothinggradients at places where you don't want them to be.

Generally, you change a smoothing group when you get to deal with hard edges, especially found on hardsurface projects. If you would give it all 1 smoothing group, you might get undesired "soft" results.
By using smoothing groups to define where the hard edges are, you keep control of how the normal information will appear on your model :)
