📍 Part of our comprehensive guide: Ultimate List of 3D Model Sites
Poly Haven is the gold standard public domain resource for 100% free, unclipped 16K HDRIs, photogrammetry PBR textures, and scanned 3D models. Dedicated entirely to the CC0 Public Domain license and funded purely by community patrons and industry sponsors, Poly Haven is an essential pillar in every modern 3D artist’s toolkit.
⚡ Platform At a Glance
Unclipped True-to-Life HDRI Skies
Most generic HDRIs found online suffer from ‘clipped suns’—where the camera sensor capped the brightness of the sun, resulting in flat, lifeless shadows. **Poly Haven** photographs all skies using specialized high-end neutral density filters to capture **unclipped dynamic ranges up to 24 EV stops**.
In Cycles, Octane, or Unreal Engine, dropping in a Poly Haven HDRI produces mathematically correct sunlight lux values and razor-sharp, natural contact shadows.
Photogrammetry PBR Textures with Complete Map Sets
Every texture on Poly Haven is captured from real-world surfaces using cross-polarized photogrammetry. Textures include full **Albedo, Roughness, Normal (DirectX & OpenGL), Height/Displacement, and Ambient Occlusion** maps at resolutions up to 8K in lossless EXR and PNG formats.
The Official Blender & DCC Add-ons
Poly Haven provides an official **Blender Asset Browser Bridge** and integrations for Unreal Engine, allowing artists to browse and drop HDRIs and materials into active scenes with a single click.

⚠️ Considerations
- Catalog is intentionally curated for quality rather than high volume.
- 16K EXR files require high RAM and storage capacity.
Frequently Asked Questions
Can I use Poly Haven HDRIs in commercial movies and games?
Yes! Because all Poly Haven assets are CC0 Public Domain, you can use them in commercial feature films, video games, TV commercials, and client projects without paying anything.
Why are unclipped HDRIs important for realistic lighting?
An unclipped HDRI preserves the true intensity of the sun relative to the sky. This allows render engines to produce realistic hard contact shadows without needing to manually add an artificial directional sun lamp.
How do I install the Poly Haven asset library in Blender?
Download the Poly Haven Blender add-on, set your local download folder in Preferences, and all assets will appear directly inside Blender’s native Asset Browser tray.
