3D artist Dorian Zgraggen created CG Bookcase, the new PBR online seamless textures library, available for free.
The site presents a wide range of standard types of materials, including metal, stones, tiles, paving, wooden floors, soil materials and fabrics.
Moreover, the artist created several unusual collections, including leaf textures, road materials and markings, as well as grunge maps for dirt, fingerprints and water droplets.
All materials come with albedo, normal, height, roughness, ambient occlusion and metalness maps up to 4K. At the time of posting, there are 380 sets of textures available, but the collection is growing steadily.
You can also download Moss, citrus and milled metal for free.
