Houdini 20.0.506 seems that splitting SSS per LPE tag doesn't work at all. Does anyone have the same issue?
attached a simple scene, if anyone want to try. thanks

Your file works as expected for me but I'm using .540.
Perhaps try with the latest daily build?

Tested builds .506 and .542. For both it works in Karma CPU, but not XPU.

That's kind of a BIG detail to omit from your original report.

There are known feature gaps between CPU/XPU

Ah, I think you've come upon a bug. Not with Karma XPU specifically but with Karma Standard Render Vars LOP - it's generating the wrong LPEs (legacy expressions that are not supported by XPU) when 'Split per LPE tag' is enabled for SSS AOV. Can you please file a bug and link this forum thread? Thank you!

You'll have to grab a daily build, it didn't make it into .547. Btw you can check out changelogs at Support > Changelog/Journal up top.
