MaterialX

MaterialX is an open standard for transfer of rich material and look-development content between applications and renderers. Originated at Lucasfilm in 2012, MaterialX has been used by Industrial Light & Magic in feature films such as Star Wars: The Force Awakens and Rogue One: A Star Wars Story, and by ILMxLAB in real-time experiences such as Trials On Tatooine.

MaterialX addresses the need for a common, open standard to represent the data values and relationships required to transfer the complete look of a computer graphics model from one application or rendering platform to another, including shading networks, patterns and texturing, complex nested materials and geometric assignments. To further encourage interchangeable CG look setups, MaterialX also defines a complete set of data creation and processing nodes with a precise mechanism for functional extensibility.

The MaterialX library, now at release v1.36.3, is an Open Source project released under a modified Apache license.
