I have made a 100% procedural Blender material called "BrickMaker"
All these brickwalls are made out of the same node tree!!
With a few rather clear parameters, it easy to change the appearance a lot.
So...after all the fun creating it I made it available on Blendermarket for $5, so others can have a go at it as well :)!
Hope you like it and enjoy the images!
