Introduction to MaterialX

With Substance Designer now supporting a MaterialX workflow it would be fantastic to see a 3DC integration.

This could be huge for next-gen game development as Unreal5’s new shader system most likely implements this system as well.

MaterialX Library v1.38.2 has been released. This release adds improved accuracy of directional albedo computations for GGX specular and Imageworks sheen, an initial shader translation graph from Autodesk Standard Surface to UsdPreviewSurface, graph definitions for the MaterialX Lama node set, an initial ESSL shader generator, support for filename templates in texture baking, initial support for GCC 11, and other fixes. Please see the MaterialX Version 1.38.2 release page on the MaterialX Github for further details, and visit the MaterialX GitHub repository to download the latest library source code, documentation and examples.

MaterialX

MaterialX is an open standard for representing rich material and look-development content in computer graphics, enabling its platform-independent description and exchange across applications and renderers. Launched at Industrial Light & Magic in 2012, MaterialX has been a key technology in their feature films and real-time experiences since Star Wars: The Force Awakens and Millennium Falcon: Smugglers Run. The project was released as open source in 2017, with companies including Sony Pictures Imageworks, Pixar, Autodesk, Adobe, and SideFX contributing to its ongoing development. In 2021, MaterialX became the seventh hosted project of the Academy Software Foundation.

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