Free PBR Textures | ShareTextures
ShareTextures.com is creating Free PBR Textures using 3D scan, from bitmap or substance designer. All textures are 1K, 2K and 4K resolution with several pbr maps which diffuse, normal, displacement, ao, etc. You can download textures without registration.
They reach 600+ textures for now and they’re adding at least one texture every day. When you become a patron you can reach 150+ alternative textures. They have several options for patrons, you can get access to their google-drive and download all textures just a few clicks. Or you can reach their ready material libraries or Real texture set collection which includes manufacturers’ textures.
