A fully procedural jungle rock face Substance material.
Everything was made entirely in Substance Designer.
I started this substance to see if making branching vines was possible without resorting to bringing in height data from elsewhere. It turns out it is possible using a sequence of tile samplers that feed into the mask of the subsequent node.
This one took a while and was really fun to work on, hope you enjoy!
EDIT: I added a version showing only the base rock layer as requested. (Thanks to Bobby Rice for that idea)
