Hello!

I have been trying to split my volume rendering scene into some different light passes, Optix fails each time and scene will be rendered on CPU. Rendering geometry and LPE's for lights works just fine, but volumes seem no to be working.

I tried this attached scene on different machines and got the same error each time. This is very light scene so it should not be a memory issue.

I am on Houdini 19.5.303

Hi. Can you try the latest daily build? There was a bug fix regarding this in 19.5.325.
