Poliigon vs Poly Haven

Poliigon provides 3D artists with a library of photorealistic textures, models, and HDRIs. The homepage describes more than 7,000 3D assets for architectural visualization, product rendering, game design, VFX, and animation. Other listed asset types include generators and Substance Designer files, with download formats such as JPG, PNG, TIFF, EXR, FBX, BLEND, and MAX. The site lists support for tools including Blender, SketchUp, 3ds Max, Cinema 4D, Maya, Houdini, Rhino, Revit, AutoCAD, Vectorworks, D5 Render, Lumion, KeyShot, Enscape, Unity, Unreal Engine, Twinmotion, and Substance tools. Polydex organizes local asset folders, identifies PBR textures, models, and HDRIs, and groups related files into single assets. Its Core plan costs nothing, billed Forever, and provides automatic identification, local search, and drag-and-drop import. Unlimited plans include premium and free library access and commercial licenses for assets downloaded during the subscription. Those plans prohibit mirroring large portions of the library or automating downloads; excessive use can restrict downloads for up to seven days.

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.
