render usd from sub lopnet in houdini

[Damien KERAUDREN]

I'm encountering an issue while attempting to render USD files from a SOP-level HDA in Houdini, which contains a usr_rop within a LOP network. The problem arises with the htorr parser, specifically showing an error message: "'SopNode' object has no attribute 'stage' at line 202 in RR_ROOT\render_apps\_submitplugins\Houdini\python3.10libs\htorr\rrnode\rop\rr_usd.py".

Is there an alternative method for exporting USD files from Houdini to render usd, aside from using a USD ROP within the default LOP context?

Best regards

So far all scenes we and customers had tested worked.

The usd_rop can be somewhere in /out or in /stage.

If you can upload a test file, I can log a bug.

 

In the meantime, does it work if you add another usd_rop in /out?

Hmm maybe they changed something in the houdini 20 api

I tried in rop and lop context and still have an error

If I put a usd_rop node in lop context (/stage/usd_rop1) and I right click -> Submit to RoyalRender I get a similar error
