Poly Haven vs Texture Ninja

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.
