Dominique Buttiens released a pack that features 25 realistic tiling textures created with Substance and based on scans.
“Spend some time creating tiling PBR textures from photographs. Making the materials was a lot of fun until I had to start cleaning up files, naming everything and presenting… I ended up with a full texture pack, so I decided to make it available to the public!”
Texture sets include the following maps: Albedo, Roughness, Normal, Height, and AmbientOcclusion.
