Thanks for the reply !
I know that it’s tire in American English and it’s tyre in British English but nevermind that typo.
It could be made just like you wrote it, but i actually think that it would have a bigger performance hit then my approach.
My approach already gives me a height map like texture which is basically a mask texture according to the 3 axes and it works kind of, (attached more images so you can see it what i’m talking about) it only needs to be converted to use the cars local space but it’s not working as it should.
Any advice?
