Hi,

Shamelessly asking before trying myself:

Volumetric Lightning and God Rays,
Possible in Karma XPU (Alpha)?

Thanks in advance.

it looks like it is possible but honestly i don't know if it would work in a production.

Interesting. Will you maybe share that scene? I do not seem to get a similar result.

It doesn't look like a volume like it does in the CPU engine, but it looks just like polygons unfortunately.

I'm sorry, I didn't remember correctly if I tried the fog box with XPU.

i had to recreate the test setup, didn't know about karma fog but it looks like it doesn't work with XPU.

Thank you.

Interesting. So don't need to enable all those extra settings on lights (such as 'Volume Contribution' in RS) in Karma..
