Hello everyone. I’m working on a car game project. I’ve added a lot of customization options to this game, but I need your help with something. Forza Horizon 4 game has a “Rim Size” customization option. In this customization option, the tire and rim grow and shrink compared to each other. I want to add this option to my game, but I don’t know how to do it. When I try to grow the wheel, both the tire and the rim grow as a whole. I would appreciate if you could help me with how I can do this.
I’m guessing they have a few different rim / tire combinations ranging from big goofy tires to super-thin rim wrappers, then they either have a clever shader to move the vertices around, or they do it in code.
They might even have the entire rim / wheel being generated procedurally at runtime based on a bunch of smoothly-changeable parameters.
