Cobblestone .sbs .sbsar PBR Substance. This is realistic cobblestone material that is suitable for any project. This is completely procedural PBR material that outputs BaseColor, Roughness, Normal, Height and AO channels.

.PNG format bitmap files are also included.

.sbs Substance source file has a well documented graph that can be easily tweaked.
