Please support the New StandardSurface Shader in Maya2020

[oglu]

We have some projects where it would be super usefull to have one shader for the game engine export and Rendering.

This is a native Maya Shader.

There's an OSL reference implementation for Arnold Standard Surface, you can try using it in our OSL material node. It's not complete from what I can see in the code.

[oglu]

Thanks for the hint Mihail. But in our case that wont help.

[^Lele^]

I'm curious, after reading the specification, of what in particular you like of that ubershader.

[oglu]

That is does export into our game engine and render in Arnold. I dont care about which shader it is.

Yes, i got that part.
I was wondering at which features specifically.

[oglu]

We use only a minimal feature set. Diffuse, Metal, Rough, Normal, Emission and Opacity.
Just standard Game PBR stuff.

[^Lele^]

Right, so why not use the autodesk physical material?
Is it not implemented in Maya too?

Regardless, what's stopping you from translating any shader into any other on export?
Particularly if you stick to PBR workflows, that should prove to be a breeze.

Which is why i was asking for *very* specific details, like some essential feature being amiss from the VRay Material.

[oglu]

You are correct there is no physical material in Maya.
We work with different departments and Outsource Studios and most of the dont use Vray.

[^Lele^]

You should keep better company then! (joking! ^^)

I still fail to see how implementing this shader would make the work less.
Meaning, you *still* need to export to an Arnold compatible format (.ass, whatever text-based bridge you may use, and so on), regardless of the starting shader in V-Ray.

"standardSurface.diffuseColor = vrayMtl.diffuse"
or
"standardSurface.diffuseColor = newADShader.diffuse"

are nigh the same effort, are they not?

I'm not being testy here, i'm truly trying to understand the request (so that perhaps i may help. ).

Wen dont use ass files. We render straight Maya files.

We like to see the standardShader in the Viewport. (does work)
We like to render the standardShader with Arnold. (does work)
We like to export the standardShader into the Game. (does work)
We like to render the standardShader with Vray.

Without doing anything to it.

Right, i see.

Hi, what render engine is this? Does it have an Arnold Standard Surface implementation, or is it a generic PBR shader?
Also, could you describe in a bit more detail how you transfer materials from Arnold to the game engine?

[oglu]

The Game Engine does have a custom exporter. Its BabylonJS.
The attached image does show the featureset of the Shader.

The new StandardSurface shader will replace the lambert1 Shader in Maya.

Its the new Maya Shader. I asume it will export also with fbx in the future.
No need for Arnold to be installed.

[oglu]

This is really really cool!
That is the lowpoly with normalmap. I just opened up the scene added two lights and hit render.

Thanks!
