That course looks exactly what I’m looking for. I’ll start it after I’m done with the “fundamentals of 3D mesh modeling“.
And yeah, that was my first attempt as well, have the treads be part of the wheel. I ran into issues when I tried to create the treads though, with parts of the tread being thicker than other parts. I tried different bevel and loop cut options, but just couldn’t get it to work. Eventually I just manually modelled the tread, and used a lattice to get it to align with the wheel. Not a clean solution, but the only one I could come up with that would make the tread even.
I’ll take a look at your demo, should definitely help. Thanks for the feedback!
