I've started modelling my first car ever just for practice on Blender. I modelled the rims (maybe not the best topology but for now I think it's almost good.)
Now I need to model the flat circled faces where the bolts are fixed, for that purpose I've choose to use a boolean with an array of a cylinder, but with a smooth shader I have the problem of weird shades, I know that it's caused by cylinder's faces that doesn't match the convex mesh of the rim but I've tried to fixed it without any success.
I've tried to use a boolean with an UV sphere with alot amount of faces and rings but even if the shades are smaller they're still there, I've tried to add more loop cuts but the problem persist and the convex face is not smooth anymore.
It's three days that I'm on it and I don't know how to do that, in C4D I use boolean with no problems why in Blender if you don't have a perfect topology you have all this problems? I'm using blender 2.9 on a new mac book pro 16''
