This is supposed to be a sci-fi truck when it’s done. If it’s done. If I can finish it before I die that is.
I have been working on the tire for a week. I have modelled it 3 or 4 times and I did not like the result. Not because I had such high standards. It was just too wrong.
I have tweaked the materials a bit. Noticed that parts of the wheel that hug the ground is smoother than the rest. So I have added roughness to the rest of tire. It is a simple noise texture though, not quite like the realistic surface imperfections.
