CG Bookcase

CG Bookcase is a dedicated online platform that offers a large collection of freely usable texture maps for 3D artists, game developers, architects, visual effects professionals, and digital content creators. The textures are released under the CC0 1.0 license, meaning they can be used for any personal or commercial project without requiring attribution or paying royalties. The collection currently contains 566 individual texture resources, each available in multiple resolution grades ranging from 1K, 2K, 4K, 6K, up to 8K, allowing users to choose the appropriate level of detail for their scene or performance requirements. The platform provides a well-organized filtering system to help users quickly find the exact texture they need. One filtering dimension is resolution, enabling a user to specify a minimum resolution (e.g., 2K) to exclude lower-quality downloads. Another essential filter is the category, which includes a broad range of material types: bark, cutout objects, concrete, fabric, floor, food, ground, leaves, marble, metal, natural stone, plants, parquet, patterns, paving, road, rock, surface imperfections, tiles, walls, and wood. Each category contains multiple texture sets, each with a preview thumbnail, a unique name, and typically a set of maps such as diffuse/albedo, normal, roughness, displacement, and ambient occlusion—though the exact maps offered may vary per texture. The presence of a “Surface Imperfections” category is particularly valuable for artists who want to add realistic wear, scratches, dirt, or smudges to their 3D models without hand-painting every detail. In addition to the main texture library, CG Bookcase includes references and guidance documents. There are dedicated guides for Blender and Unreal Engine, two of the most popular 3D crea
