USD and materialX


Now this looks interesting. The first implementation that seems useful out-of-the box without the help of an in-house programming department. They even provide binaries for linux. Cool. I will definitely play with that.
But I wonder if Autodesk will implement some USD or MaterialX stuff natively in Maya2019, more aimed at a general audience and not so studio specific.

Edit: The walter standin can also load standard alembic files. So it’s useful even if you don’t use usd. It’s like gpuCache on speed, with attribute overrides, material assignments, hydra viewport rendering.



mate think u can recompile it for win?


That seems not like an easy task. Nothing I would like to spend my rare free time with at the moment. USD itself, while having been successfully compiled for win, is not officially supported by the devs on that platform.
And since we use Linux at work nobody would allow me to get Walter running on Windows during work time.

I also already lost a bit of interest in Walter. When testing it I found out that it does not like some of our shading networks. It uses abcMaterial to store shaders which errors out on our complexer networks. As with all the USD tools up until now it seems again very specific to the work flow of the company it was designed in.


i hope we dont have to wait to long until Autodesk, Pixar, Luma and AnimalLogic get there combined version running.
But i assume we wont see it before Siggraph 2019.


I’ve read about that collaboration in some comments too. Is there any official announcement? I wonder what Autodesks plan is. The tools of those 3 companies all have the goal of exporting from maya to go into houdini and katana for lighting and rendering. Not something Autodesk would like to support I guess. Walter is the only tool I know at the moment that allows you to render USD from inside Maya with Arnold.


I would say they have to. Otherwise they get kicked out of the big pipelines. Same for matX.


Its official but no announcement outside of the Siggraph talk.


ah too bad :slight_smile:


MaterialX Slides from Siggraph are now online.


ShaderX from Autodesk is now merged into the master.


Just a hint.

There is a precompiled USD/matX version on Github


The first drop of the Autodesk USD for Maya is on GitHub now.

Why yet another Maya plugin?

As USD gains in popularity many studios have been wondering what plugin they should deploy within their pipelines. Two popular choices, used individually as well as together, have been the Pixar USDMaya plugin that has been part of USD itself, and Animal Logic’s, which was separately released as Open Source. Both plugins have a strong community of users, but some have questioned when Autodesk would eventually release an officially supported plugin themselves. The goal of this project is to work directly with Pixar and Animal Logic, as well as other key contributors, in order to merge the best of both into a single supported plugin.


Some great overvie from Siggraph

Some hints about how the new mat edtor in maya could look like.


Slides from the BoF talk.


good finds Chris, thanks for that.


An other one


Great read…


Siggraph 2019 Slides from Pixar.

Hydra is an interesting concept.


Pixar is goin to release the latest USD v19.11 and handing the Maya plugin over to Autodesk.

  • Deprecated Maya plugin in favor of the Autodesk maya-usd plugin available at We anticipate removing the plugin from the USD repository in the next release and recommend users begin transitioning to the Autodesk plugin – it contains the same features as the Pixar plugin (in fact, it is the same code).


The Autodesk Siggraph Talk is now online.
