Vintage Ceramic Tiles

Another Substance Designer exercise, this time "freestyle", meaning without tutorial, just trying to figure out myself how to get the results I wanted, and for the most part I'm quite happy with it. Also learned how to (and how not to) do some things, of course, and will try to do them better with the next project.
It has a bunch of adjustable parameters, the tiling, pattern, colors, amount of dirt and surface cracks, roughness etc. can all be changed more or less dramatically, I want to still tweak some of them to make it more flexible. Might share this later on substance share, once I'm happy with the exposure of all the parameters.
