Houdini and Karma XPU - HUSK
As of Houdini 20.5, husk no longer pays attention to the render delegate from the render settings primitive. You must specify on the command line to husk
-R BRAY_HdKarmaXPU
If you select "gpu" when submitting on the farm it will add the appropriate flag (tested 3/9/2026)
You can also command line render locally using husk -R BRAY_HdKarmaXPU or --engine xpu
To render locally to test a frame use command line render to ensure your usd file is working before waiting in queue on the farm.
If you are working in GUI things will be rendering in xpu but
husk renders will not without the above flags, despite your
settings.
