I assume you should be able to use background B event in LPE
You obviously not get the refraction information but you should get the background contribution for the chosen lightpaths

Hello @tamte, Thanks for this but don't quite understand how to set this up.

I've added two images here, the one with black shows what I get If I just render the object with nothing in the background and the one with the white bg and white showing in transparent areas is me putting a grid object behind it it the render.

But I want to be able to render with nothing behind it and get the transparent areas instead of black to use this image on a website.

I've also added a hip file if you have the time to show how to set this up.

Thanks much!

how to render an object with transmissive materials and get the alpha to respect the transparency in karma XPU?

by default the transmissive areas just renders black!

you know, Houdini viewport has been a massive disappointment ever since I started using it. But previously, it was at least still usable. In H20.5 It's a downright disgrace for such an incredible DCC. This rotating glitch bug bullshit has been in H20.5 since its release and I don't think something like this should need to be reported more than once for it to be fixed.

@sideFX the damn software is unusable if the viewport doesn't work!!!!!

Killing the scene view and opening it doesn't cause it to go away. Man I'm tired of these silly persistent viewport bugs. It's garbage! it's been years. A new viewport, same crap; oh no wait, much worst crap!
