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_...

We're excited to share #OpenPBR Volume, a new collaboration between Autodesk and Sidefx to create an open standard enabling users to define the look of volumetric assets. OpenPBR is a subproject of @materialx.bsky.social. Read more: www.aswf.io/blog/openpbr...

New at #SIGGRAPH2025: Can we make Perlin Noise stretch along some underlying vector field? Well it turns out it's possible with two simple additions to the original method! No need for advection or convolutions. Find the paper and implementations here: github.com/jakericedesi...

The HPG 2025 Conference starts tomorrow, and I'm looking forward to the MaterialX talk from my ILM colleague Alain Hostettler, the RenderMan XPU talk from Pixar, and the Slang talk from @shannonin3d.bsky.social. highperformancegraphics.org/2025/program...

The SIGGRAPH Physically Based Shading course is back this year: blog.selfshadow.com/publications...

This was a really fun conversation on MaterialX, glTF, and OpenUSD at the Metaverse Standards Forum last week, and I thought I'd share it here for interested folks. www.youtube.com/watch?v=m-bE...

One update we want to celebrate in USD 25.05 is having MaterialX v1.39.3 -- which includes OpenPBR Surface and the Chiang Hair BSDF -- as the new default MatX version. 🎉 Thank you for the close collab @materialx.bsky.social! 💖 We're excited to see the cool things folks create with this combo!

Join the 3D Asset Interoperability Working Group on April 30th for the education session, Material Convergence - MaterialX, glTF, and USD with Jonathan Stone and Ed Mackey. All members are welcome! Not a member? Join us - metaverse-standards.org/members/ #glTF #MaterialX #USD

Happy twentieth to the Psychonauts crew, an amazing game team that I remain deeply proud to have worked alongside. Thanks to @timoflegend.bsky.social, @erikrobson.net, @doubleanna.bsky.social, @keescheese.bsky.social, @scottlava.bsky.social, and the rest of this brilliant band of troublemakers.

Are you interested in contributing to an #ASWF project but don't know where to start? Join us on May 15 for #DevDays and spend one day learning about a project, benefiting from the mentorship of project leaders, and of course writing code! Register at devdays.aswf.io.

The call for presentations for #ASWF Open Source Days is now open until May 18! We are expecting a full house again this year with 250+ software engineers from across the motion picture industry. Submit your talk at aswf.io/opensourcedays

EON: A practical energy-preserving rough diffuse BRDF; by Portsmouth, Kutz, and Hill. www.jcgt.org/published/00...

Implemented USD point instancer primvar support in my toy renderer the last few days. Can now render this 2D Gaussian Splatting (2DGS) scene with a single mesh & MaterialX material. (Created by Oliver Markowski with Houdini, link see below ⬇️)

Did you know that many of the Academy Award winners and nominees used open source software? Learn more about some of the open source tools used on films like Flow and The Wild Robot at www.aswf.io/blog/this-ye... #ASWF #opensource #VFX #animation

Although it’s a small set of updates, I’m particularly proud of this latest release because it resulted from a collaboration between the @openusd.bsky.social and @materialx.bsky.social projects, with the goal of making MaterialX v1.39.3 the new default in USD 25.05.

We're proud to welcome our parent organization, @academyswf.bsky.social, to Bluesky, and we hope you'll follow them if you're interested in related projects such as OpenEXR, OpenColorIO, and Open Shading Language!

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. github.com/AcademySoftw...

MaterialX v1.39.2 has been released! This version adds support for the Chiang Hair BSDF, Disney Principled shading model, generic color ramps, improved Worley noise, shader generation optimizations, and contributions from our participants in ASWF Dev Days 2024. www.aswf.io/blog/materia...

The first release candidate for MaterialX 1.39.2 has been marked on GitHub, and we're encouraging teams to test it out over the next week. The tag for this release candidate is v1.39.2-rc1, and the latest changelog may be found at github.com/AcademySoftw...

It took me a while but I finally finished to recode the 300 programs of Jean-Paul Delahaye’s book "Nouveaux dessins géométriques et artistiques" with p5js. The book was published in 1985 and features classic generative algorithms. github.com/v3ga/nouveau...

Congratulations to our colleagues at OTOY for this initial preview of MaterialX support in Octane Render 2026.1: render.otoy.com/forum/viewto...

Highlighting this post from @shannonin3d.bsky.social, we're very interested in the possibilities for Slang in MaterialX, where it could be used to harmonize node implementations across GLSL, HLSL, MSL, WGSL, and other hardware shading languages. shader-slang.com/blog/2024/11...

It would be amazing to see the computer graphics community engage on Bluesky, so here's a starter pack for those who might be interested in joining in: go.bsky.app/K8ZL1kq

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! github.com/AcademySoftw...

For any developer who is interested in contributing to an Academy Software Foundation project, perhaps for the first time, I wanted to highlight ASWF Dev Days 2024, which will take place on September 26-27. We hope to see you there! www.aswf.io/blog/devdays...

I'm so excited for y'all to see #TheCreator. We've been secretly working w/ Gareth Edwards along w/ Prod Designer James Clyne & photography from Greig Fraser & Oren Soffer. I'm extremely proud of this as it's my 1st time being VFX Supervisor w/ the ILM dream team! https://youtu.be/573GCxqkYEg
