It aims to provide a material representation capable of accurately modeling the vast majority of CG materials used in practical visual effects and feature animation productions.\n\nOpenPBR Surface is an open standard hosted by the [Academy Software Foundation](https://www.aswf.io/) (ASWF), and is organized as a subproject of [MaterialX](https://materialx.org/).\n\n### Specification\n\n* **[White paper](https://academysoftwarefoundation.github.io/OpenPBR/)**\n* **[Parameter reference](https://academysoftwarefoundation.github.io/OpenPBR/#parameterreference)**\n* **[Reference implementation](reference/open_pbr_surface.mtlx)** – written in [MaterialX](https://materialx.org/)\n* **[BibTeX citation](openpbr.bib)**\n\n### Resources\n\n* [MaterialX Web Viewer](https://academysoftwarefoundation.github.io/MaterialX/?file=Materials/Examples/OpenPbr/open_pbr_default.mtlx) - WebGL rasterization renderer using MaterialX [implementation](reference/open_pbr_surface.mtlx) of OpenPBR\n* [OpenPBR-viewer](https://github.com/portsmouth/OpenPBR-viewer) - self-contained example implementation in a WebGL pathtracer (run [here](https://portsmouth.github.io/OpenPBR-viewer))\n* [#openpbr](https://academysoftwarefdn.slack.com/channels/openpbr) - public Slack channel for discussions, hosted by ASWF\n\n\u003cbr/\u003e\n\n[![License: CC BY-SA 4.0](https://img.shields.io/badge/License-Apache%202.0-informational.svg)](LICENSE)\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Facademysoftwarefoundation%2Fopenpbr","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Facademysoftwarefoundation%2Fopenpbr","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Facademysoftwarefoundation%2Fopenpbr/lists"}
