Nvidia Omniverse Hydra delegate Vray?

[Filib]

Hello everyone,
im currently testing Nvidia Omniverse which is a proof of concept and could chance the way of working in 3D using USD, Hydra and MDL / Xmaterials in my opinion.

I have seen Renderengines try to archive a hydra standard and i read that vray is doing this too e.g. Houdini Vray for Solaris ..
Is there any plan for Vray to use it inside of Nvidia Omniverse as a delegate Renderengine? I would like to test it as soon as possible

Cheers Philipp

Hey all,

We already have a functioning V-Ray Hydra delegate that can be used with the Omniverse Create SDK - you'll need to ask Nvidia for access to that one.
On the V-Ray end, you will need access to our V-Ray for USD (Nvidia) nightly builds. You can ask the support team for access - if you decide to do so, please ask them to include me in the communication. The exact link they need to provide you with access to is this:
https://nightlies.chaos.com/#/vray5usd_nvidia/nightly

Once you have both of those set up, starting Omniverse Create with V-Ray working inside is pretty simple - you can launch the 'create' app with a bat file, e.g.

:: V-Ray For USD Omniverse Launcher
::
echo off

setlocal

:: CHANGE THIS PATH TO YOUR DELEGATE LOCATION
set PXR_PLUGINPATH_NAME=%~dp0/vray_adv_52020_usd_v20.08_py37_2f78ee0_omniverse_3 3_windows/plugin/usd

:: CHANGE THIS PATH TO YOUR OMNIVERSE LOCATION
"%~dp0/create-launcher@2022.1.0-rc.4+2022.1.3156.711dfda0.tc.windows-x86_64.release.signed/kit/kit.exe"

endlocal

A couple of things to note:

1. I was using the 511.79 NVidia driver when testing.
2. There's an issue with the console getting flooded with shader compilation errors when you select an object in the Create app outliner
3. Light parameters coming from USD are ignored - I had to manually update the texture paths, intensity and color settings
4. Render settings coming from USD are ignored - you'll get V-Ray running with pretty much default settings only

Hope that helps!

Thanks for the update. Great to see there is been worked on. Its to experimental for now. I will check it out if its public available.

Hey oglu ,

Sure, we're actively working on both the Hydra delegate and direct USD rendering (so you could use vray.exe with USD files in addition to VRScenes).
You could give the Hydra delegate a spin in Houdini's Solaris.

Best regards!

Awesome! thanks for your information!!!!
