Dark Stone Wall PBR material, including 3 different stone color randomizations.
100% Substance Designer. Full size renders here: https://www.artstation.com/artwork/oO0y3w
The texture set was also used as base for the walls of castle Weiler: https://www.artstation.com/artwork/EVYYG0
includes 3 Basecolor (or Diffuse) maps, 1 Height, Bump, Normal and Roughness map as well as a stone/mortar mask for easy editing. All maps are 4k and 16bit.
Packed as 500 MB ZIP file containing 8 PNG images.
Edit: The 3 basecolor variations are not shown here. They only consist of a reshuffling of the existing stone colors. I mixed the 3 maps to avoid visible repititions on large surfaces of the same wall. They are not color variations in the sense of completely different types of stones or walls.
