here are some materials I amde with substance designer and zbrush.
About the stone amterials I first sculpted in zbrush the array then I bake the high to do a tilled texture into substance designer.Thanks to substance designer I made some generator to add stone reliefs, voronois pattern and cracks.
Roof tile / wood and ropes has been made in substance designer then refine everything in substance painter.
Hope you'll like it.
