I downloaded some megascans assets which render fine with H20, but lock up/crash H21. H21 is definitely not liking the hierarchy as shown by the exclamation mark in the 'Kind' column in the Scene Graph Spreadsheet. I did try fixing it with a configure primitive lop but it still crashes.
The offending USD file is attached, as is an accompanying .json file (I believe it determines animated values for wind).

Has anyone encountered something like this?

H20 Render:


H21 Fail:


H21 Fail with reconfigured prims:

Can you please log this as a bug for us to investigate? Also, it looks like that USD file references a leaves USD file that isn't in the attachment.

Thanks Rob, I have submitted a bug: "Megascans usd file crashes Houdini".

Attached is the foliage file that is referenced as well, sorry for not including it in the original post (it is included in the ticket though).

Just noting this also happens in 22.0.368
