Toon Render Element Channel in Solaris?

[marc_cacciola]

Is it possible to render toon channel separately as AOV in Solaris? I the regular workflow I make the vraytoon in the env and check "toon render elements only". I looked at the vray standard rendervars and cannot find a "toon" channel...

I have been able to hack a toon channel by creating a seprate solaris render branch and just applying a flat white material. I would prefer to have the exr come out together for compositing...

Any help or advice is appreciated. Thank you

A related question would be, how can one add toon lines per primitive or exclude certain primitives in Solaris?

Hey marc_cacciola ,

There's a demo scene and a short guide on working with toon in Solaris here: https://docs.chaos.com/display/VRAYH...ect+in+Solaris

As to the Toon AOV - the name for the RenderVar prim would be "toon" - I've attached a screenshot and the example scene. We'll update the Standard Render Vars LOP, thank you for the heads up!



Best regards!

Thank you Gosho! Thats is almost what I meant but to make it clearer I do not want the toon visible in the beauty pass only as an AOV so that the toon effect can be added and adjusted in post. In your file I still see the toon effect in the Beauty pass. This is possible in the old/ non Solaris workflow....

Oh I figured it out, in the material override I can check the "Toon Render Elements Only"

A follow up to this would be. In Solaris how does the "Include/Exclude" workflow work? In this workflow every material has to have a usd_env_toon added, before this was added as an environment seprately and objects could be included or excluded.

Hey marc_cacciola ,

Indeed, node lists for material/shading effects are quite tricky to handle with Hydra as you need the viewport rendering to be able to run continuously. Thus we opted to provide a material-based workflow for the Toon effect, just like other integrators.

If you need to replicate the 'vanilla' Houdini workflow, may I suggest simply enabling Toon on the Render Settings LOP - this will apply it to all objects in the scene. You could then override with a material-based toon effect on a per-object basis, if needed. The same could also be achieved with the Render Geometry Settings LOP for a collection of primitives.

Best regards!
