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 http://img.archiexpo.com/images_ae/photo-g/metal-facade-cladding-aluminium-extruded-panels-73074.jpg
. Also why the checkers one doesn't look like one checker up and the other one down instead of a line between them?
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!
