USD and materialX


#21

cause we dont use USD files…
and USD feels very renderman centric… :wink:

and i assume maya will support matX native…


#22

Okay so we have four or six new “standards” that are all basically competing, attempting to unify shading across platforms - by doing the exact opposite.

Yeah, this stuff is just silly.


#23

i see only two and they try to solve two diffrent things in the shading…

USDshade is the build in solution and does move shading around in USD renderman land…
USDshade does fit the needs for pixar…

and materialX is is a shading creation and managing platform… wich does not need USD… but can replace USDshade if you wish…
mX does fit the needs for ilm…

both are created by the mothership disney…

if someone is at Siggraph there will be a talk about matX…

[quote=]As mentioned before, we will be holding a MaterialX Birds-of-a-Feather session at Siggraph 2018 in Vancouver, BC:

RodeoFX opensourced its inhouse USD plugin Walter for maya.

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.

@colt

mate think u can recompile it for win?


#31

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.


#32

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.


#33

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.


#34

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


#35

Its official but no announcement outside of the Siggraph talk.

@Colt
ah too bad :slight_smile:
