I was too eager to test the 2.2 final, so even thou you finally didn't add the tile procedural, I could come up with this, with a little more effort they could look good.
But what I don't understand are 2 things, first why the saw wave does make that type of bump? and not one more like this

Also why when I add the bump map, doesn't matter the intensity of it, fireflies pop like crazy?
Hehehe, this is gonna be a lot of fun testing all the procedurals!
