Houdini and Karma XPU
Posted March 7 2026XPU and husk rendering
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
That means that currently on the farm only cpu is available. This will be addressed soon and I will update the post once tested.
In the meantime you can command line render 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.
