How to Shader override in Solaris

[martinkindl83]

Hello.

We are slowly moving to Solaris for production and i came to the stop, while trying to add globam material override.

I would like  my whole scene to be rendred as greyshaded.

Normally i would use Material Operator (not supported in Solaris) or use Shader override from Arnold render settings (no tbeing present in Solaris).

I cant drop material assigns, as i have instance prototypes, which stops me from doing that.

Any thoughts?

Hi Martin

Maybe with the Material Linker LOP ?

Hello Stephen.

Its not possible as i have references and point instances in the scene.

I was looking for the same functionality as we have in HtoA, where we can override all shaders

Hi Martin, we're currently working on exposing this feature in HtoA. We're hoping to make this available in a future HtoA release

[martinkindl83]

Thank you. Have seen it in beta. Haven't had chance to test it

[sebastien.blaineau.ortegaHRM3U]

what you've see in beta is just the usd part, the integration in HtoA is still in progress.

Hello.

Can i please check how we are looking for shader overrides and operator support in general?

Hello,

If you have references (assuming you mean "Asset Reference" nodes) then you should be able to see the materials for them in the Scene Graph?
In which case you could do an "Edit Property" on those materials base colour, etc. to modify them using wildcards etc. or create a new material and wildcard assign that to the references feeding the point instancer.

edit property example

assign new material example

Maybe I'm misunderstanding the scene setup however!

best,

Hi, 
We too are in the same boat and are currently moving all our production work to Solaris using Arnold.

In order to have the whole scene rendered using a grey shader, currently we use the unassignmaterial LOP node along with Houdini Primitive Patterns to globally unassign all material bindings followed by a Material Library LOP with the grey shader and again use Houdini prim patterns to assign the grey shader. You may have to tweak the prim patterns depending on the USD prim types in your scene.

Hope this helps in the interim while Arnold devs implement a global shader override.

Best,
Vidu

Thank you very much!

hello.

non of the above solutions solve the problem for us.

What we are looking for, is the same functionality as on Arnold Render rop, to be able override from single place all shaders in the scene.

And support for Operators

As we already said previously, this feature request is on our radar and we're hoping to get it done.  It had to be postponed a bit due to higher priorities, but it's still a feature request that we want to tackle. The suggestions that were done are means to workaround the missing feature, but they won't completely replace it. So this thread shouldn't be resolved yet

thank you Seb
