Nice. I think the code is at https://github.com/NVIDIAGameWorks/rtx-remix for those interested.

I had played with version 0.0.1 trying to get it to work with https://www.freeallegiance.org/, but ran into issues. I'm glad to see they are improving the documentation. I'll have to try it out again.

Yeah this is neat but it is 90% not done and that is being generous.

For a open source path tracer with a full glTF compatible material model and lighting and runs in the browser check out:

Or if you want hardcore features look at Moonray from Dreamworks:
