Lol they’re suppose to have a separate bone my dude. They can’t have the same bone as the wheel if you don’t want them spinning along with it. Calipers never spin with the wheel, if you’ve ever noticed. Hence the convoluted nodes there in the screenshots to try to get them to emulate the Z-rotation of the wheel while remaining stationary in all the other axis. Unless you know a trick that I don’t know, they’re supposed to have their own.
The model isn’t badly rigged. That would be the first thing to check, of course. Each bone correctly moves the corresponding mesh as expected, and they’re all named appropriately. That’s not the issue here.
Here’s my bone hierarchy
Here’s the naming convention. CFL (Caliper Front Left) is supposed to get rotation from FL (Front Left)
The only thing I’m not clued up on however is the ‘sharing the same axis as the wheels’ part. How/where would I check that?
