FreePBRTextures vs Poly Haven

FreePBRTextures is a web library of free, seamless physically based rendering materials for game developers, 3D artists and designers. Its homepage lists more than 30 textures across eight categories, each generated at 4K resolution, or 4096 by 4096 pixels. Every texture includes albedo, normal and roughness maps. Procedural generation uses mathematical noise functions, with wrapped coordinates producing tileable edges; a seed recreates the same result, while changing seeds and parameters makes variations. The site also describes combining AI image generation with procedural post-processing. The textures are released under CC0, which permits commercial use, modification and redistribution without attribution. Blender and Unity workflows can use the albedo, normal and roughness maps; a guide for Unreal Engine 5 also uses metallic maps. The free plan costs nothing and requires no signup. Files are provided in PNG and ZIP formats. The terms page describes itself as template terms and advises customization and legal review.

Poly Haven is a curated public library of HDRIs, textures, and 3D models for visual effects artists and game designers. Its assets use a CC0 license and can be used commercially. The library describes its HDRIs as 16k+ resolution and unclipped, and its photoscanned seamless PBR textures as at least 8k. The public collection costs nothing, with no paywall or signup required. A Blender add-on brings assets into the software's asset browser and provides organized catalogs, resolution switching, automatic texture scaling, and one-click displacement setup. Poly Haven also offers an API whose default endpoints are free for personal, academic, and commercial use without login or an API key. Live API users must provide clear attribution and a unique User-Agent header. The organization says its assets are made by humans, avoiding generative AI and overreliance on procedural methods. Optional paid offerings include Vault access for $3 a month, a Blender add-on via Patreon for $5 a month, or an identical add-on via Superhive for $49, paid once.
