CGBookcase vs Free Stock Textures

CGBookcase is a free web resource for physically based rendering textures and material guidance. Its catalog lists 566 free textures with filters for 1K, 2K, 4K, 6K, and 8K resolutions. Textures use the CC0 1.0 license, allowing free use without credit, including commercial work. A listed Manhole Cover 16 material includes Base Color, Height, Mask, Metallic, DirectX Normal, and Roughness maps. The site also provides the open-source Texture Tiling Tool, which helps make photoscanned surfaces seamless and repeatable through surface-aware blending, clone patches, and lighting equalization at seams. Guides cover Blender and Unreal Engine setup. The Blender guidance notes that DirectX normal maps need green-channel inversion for Blender’s OpenGL format. Sample Rock and Bark downloads are offered in 4K and 8K, with file sizes from 118MB to 958MB. Patrons can access a Google Drive folder containing all textures.

Free Stock Textures is a web library for browsing and downloading photographic textures, images, and photos. Visitors can search the collection or use categories including abstract, concrete, graffiti, ground, grunge, liquid, metal, nature, stone, wall, and wood. The site says published photos use Creative Commons Zero, allowing commercial use without crediting the photographer or source; linking back is not required. The free plan costs nothing. Registered users may download up to 50 textures per day, while anonymous users may download up to five. After reaching the daily limit, downloads from that IP are blocked for 24 hours. The terms describe Premium as paid access to the full collection under applicable image licenses, while prohibiting subscribers from building a local collection that imitates the website. Most photos receive Lightroom adjustments such as cropping, clarity, vibrance, and exposure.
