This is one of the first PBR rock surface I shot and processed for the Plates Creek project. I made multiple shots into a "reference" small creek for that project and this surface is part of them, was on the ground spawning across several meters. Its comes in two variations as I usually shoot a rectangle area for that purpose.
*Update*: this surface has been reprocessed at 8K with 10 texture maps per variation and is now available on the Artstation Marketplace:
Scales variation A: https://artstn.co/m/XmNL
Scales variation B: https://artstn.co/m/xK8a
Scales variations A+B: https://artstn.co/m/p8WV
