What CGBookcase is

CGBookcase is a web resource for free PBR textures and material-making guidance. Its catalog lists 566 textures and lets users filter by resolution from 1K to 8K. The textures use the CC0 1.0 license, allowing free use without credit. Material pages can include several map types; Manhole Cover 16, for example, lists Base Color, Height, Mask, Metallic, DirectX Normal, and Roughness maps. The open-source Texture Tiling Tool helps turn photoscanned surfaces into tileable textures using surface-aware blending, clone patches, and lighting equalization at seams. CGBookcase also offers a Blender guide covering material maps and an Unreal Engine guide for importing maps and setting up materials. The Blender guide notes that DirectX normal maps require a green-channel inversion for Blender's OpenGL format. Sample Rock and Bark textures are offered in 4K and 8K, with listed file sizes from 118MB to 958MB. Patrons can access a Google Drive folder containing all textures.
