Thanks to our colleagues at Autodesk, IKEA, NVIDIA, OTOY, and Pixar Animation Studios for their amazing work on the MaterialX and OpenPBR Virtual Town Hall for @aswf.io Open Source Days 2025.

The full slide deck can be found at materialx.org/assets/ASWF_...

Highlighting one talk at this event, Johan Bowald from IKEA will present new work on Shader Translation Graphs in content production.

The two renders below are of a MaterialX cloth material, with the original Standard Surface on the left, and the glTF PBR translation on the right.

Join us on August 5th for the MaterialX Virtual Townhall at ASWF Open Source Days 2025, featuring presentations from Autodesk, IKEA, Lucasfilm, NVIDIA, OpenPBR, OTOY, and Pixar.

MaterialX v1.39.2 also brings improvements to the classic Worley noise technique, contributed by Chris Rydalch at SideFX and seen here in Karma for Houdini.

Another key contribution is generic color ramps, authored by Jonathan Feldstein at Autodesk and seen below in Arnold for Maya, allowing a new level of flexibility for color controls in MaterialX graphs.

Highlighting one of the key contributions in MaterialX v1.39.2, Masuo Suzuki at NVIDIA contributed the Chiang Hair BSDF, seen below in NVIDIA RTX, which opens the door to the authoring of cross-platform, customizable hair shading models in MaterialX and OpenUSD.

I wanted to highlight this recent proposal from Masuo Suzuki at NVIDIA, adding support for Mikkelsen's classic Hex-Tiling technique in MaterialX.

We'd love some feedback from the graphics community on this proposal!
