Karma - objects missing in output. Sept. 28, 2026, 5:53 a.m.
If this is reproducible, can you send us the hip?
Strange USD Crash in H21 Sept. 24, 2026, 3:54 p.m.
Thanks ... I checked another random Megaplant and it has the same issue. I'll see if we can reach anyone on that team to discuss.
But yes please do give 22.0.453 a spin when it's available tomorrow.

Strange USD Crash in H21 Sept. 24, 2026, 6:43 a.m.
This is an issue with bad USD data, which only shows up in Hydra2 (H21+). The ueJointNames data is advertised as being of type token but in the binary USD file it's actually being stored as string.
It'd be useful to know how this file was generated, in case there's likely to be a lot of such malformed files out in the wild.
In terms of making things work:
- we're patching Karma to not crash on this (it'll emit a warning when it notices this)
- you can use usdcat to convert the .usd -> .usda and then usdcat to convert it back from .usda -> .usd (which will properly encode the data as token)
