solaris light linker seems a bit glitchy Dec. 22, 2023, 3:55 p.m.

Hey Brian,

I filed a bug report for this with a scene file and example video. Bug 133880. Hope it helps!

I'm experiencing the same issue with light linker and XPU, sadly no one has replied to this post since it was posted :[

Yes, I experienced the same.
Tends to break easily when changing things in the node tree.
Randomly not rendering linked lights as well.

Hi guys

thanks for the feedback.
Is it possible you could file a bug with an example scene + exact repro steps?
With that, we can get this fixed


Hey Brian, I found this post while searching to see if anyone else is running into this issue. I have a simple scene that I will package up and submit this week. Not limited to XPU - appears to be a general Karma bug.

To be frank, I don't feel very motivated to track down a bug in 18.5.462 that is already fixed in 18.5.499

Totally hear you on this, and it makes sense. My big holdup is waiting on 3Delight to build against 18.5.499 (which will happen soon). That's why I put the issue forward with 18.5.462, to at least see if anyone knew what was happening.
