CGBookcase
What it is
CGBookcase is a web resource for free PBR textures and material-making guidance. Its catalog lists 566 textures, with filters for 1K, 2K, 4K, 6K, and 8K resolutions. Textures are published under the CC0 1.0 license, allowing use without credit, including commercial use. Materials can include several map types; the Manhole Cover 16 material lists Base Color, Height, Mask, Metallic, DirectX Normal, and Roughness maps. The open-source Texture Tiling Tool helps make photoscanned surfaces seamless and tileable using surface-aware blending, clone patches, and lighting equalization at seams. CGBookcase provides guidance for setting up materials in Blender and Unreal Engine. Its Blender guide notes that its DirectX normal maps require inverting the green channel for Blender's OpenGL format. Sample Rock and Bark textures are available in 4K and 8K, with listed file sizes ranging from 118MB to 958MB. Patrons can access a Google Drive folder containing all textures.
