A mossy rubber tiles floor material with moss and adjustable parameters (moss amount, pattern variation, water level, dirt amount, custom moss mask, etc.). 100 % done in Substance Designer and rendered in Marmorset. You can get a commented substance graph of this material (as well as the .sbsar file and pre-exported textures) on gumroad or my artsation store:
I described and commented every step of the creation process in the .sbs file, so if you are interested how to make a material like this or if you need it for a project visit my gumroad or artsation store page.
I hope you like it and feel free to c&c :)
