The noise texture and the nodes connected to it are somehow not working; the black and white rings are not showing up on the ring at all and I don't know how to fix it. Any help would be appreciated!
Surpassing the mapping node altogether, and then rejoining them all again fixed it for some reason.. though I still don't know what caused the problem in the first place
It might be the origin point of the object, it might be the scale. The thing when working procedurally is that it depends on other things apart from the nodes themselves. So yes a couple of screenshots could help and try describing what you're doing so we can try and spot the error.
