Beauty shot showcasing the Aging process with a percentage of the old bricks replaced by new ones
Aging process gif. Can be global or mask-driven, and it also has a parameter to modify the old-to-new brick replacement amount
Dirt process gif. Can be global or mask-driven.
Tile Generator as the base bricks structure allows for interesting pattern generation.

Substance graph. i've tried to keep it as tidy and simple as process but the erosion shape and the various features required some extra nodes.

This poor limestone wall substance has been sitting in my hard disk for over one year now until I finally had time to give it the love it needed. I've tidied the graph up, simplifying certain features generation, and extracted the mortar as a separate material. I've focused mainly on the Age and Dirt parameters (they both can be global or mask-driven), as I tried to capture the look of old churches walls here in the Oxfordshire, with different portions of the wall being eroded and dirtied at different speeds and new bricks replacing the ones that are too old and broken.
