Best you send us the scene along with the .usd and its instance so we can take a look. Mention me and include a link to this thread.

Filled a bug. #16770

Thanks for the provided files. How was the geometry instanced? nParticles and Instancer?

With Bifrost. But this version is not available to the public.

Okay, I see. Just so you know, I’ve logged the issue (internal bug-tracker id: VMAYA-10965) for investigation.

Thanks!
Do you see the scattered robots in the viewport? Just to make sure the setup does work.

Some extra info.
The file is created with Maya_USD 0.15

Yes, they are visible in the viewport, but not when rendering.

Thank you, I’ll add it to the log.
