Hi!

Been quite a while since I've been on here, was a regular on the site about 10 years ago, just getting back into Maya after 10 years of working as a playground designer for schools, now looking to get some practice in and eventually get a portfolio together with the hopes of getting out of my current job! lol

Got a question if anyone can help, used an aisurfaceshader to make this chrome material but want to add dirt/scratches etc, basically texture a layer on top of it, any help for the best way to do it?
Not super experienced in shaders, trying to build up my knowledge!

Any help much appreciated.
