# PolyScan

> PolyScan provides free CC0 PBR textures, 3D models, and browser-based tools for 3D artists, technical artists, and game developers.

PolyScan is the display name. The website is hosted at `polyscann.com`.

Important notes:

- PolyScan assets are released under CC0 1.0 unless an asset page says otherwise.
- CC0 assets may be used in personal and commercial work without attribution.
- Studio tools are free to use and do not require an account.
- Studio pages state when files are processed locally in the browser.
- PBR maps include albedo, normal, roughness, metallic, ambient occlusion, and height or displacement maps.

- [Texture Channel Packer for ORM and Mask Maps](https://polyscann.com/studio/mask-map-generator.md): Pack AO, roughness, metallic, and smoothness into ORM, RMA, Unity HDRP, or URP textures.
- [PBR Texture Generator](https://polyscann.com/studio/texture-generator.md): Convert a photo, albedo, or color texture into normal, height, roughness, and ambient occlusion maps.
- [Normal Map Generator from Image](https://polyscann.com/studio/image-to-normal.md): Create an OpenGL normal map from a photo, albedo, or color texture with a browser-based neural model.
- [Normal Map to Height Map Converter](https://polyscann.com/studio/normal-to-height.md): Convert an OpenGL normal map to a height or displacement map in the browser.
- [Height Map to Normal Map Converter](https://polyscann.com/studio/height-to-normal.md): Convert a grayscale height or displacement map to an OpenGL normal map with a Sobel filter.
- [Ambient Occlusion Map Generator from Height Map](https://polyscann.com/studio/height-to-ao.md): Generate an AO map from a grayscale height or displacement map with browser-based HBAO.
