Nvidia Warp Cloth model

Omniverse Isaac Sim

Hello!

I have been trying to reproduce the Warp Cloth Example that was shown in the Office hour stream two weeks ago.
The existing example worked fine but when I rebuilt it, the cloth just behaved very strangely (got a spikey shape, did not fall down or anything) and I got an error:
"/World/ActionGraph/bundle_inspect_changes: [/World/ActionGraph] OmniGraph Error: Required bundle outputs.bundle is invalid, compute skippd (from data_base_valid() at line 226 in home/user/.cache/ov/ogn_generated/1.79.1/omni.warp-1.5.0/omni.warp.nodes/ogn/OgnBundleInspectChangesDatabase.py)

Is there a tutorial that I can follow to really understand how the warp integration works?

Thanks in advance!

Could you please share the video link along with the specific start time for the example you were referring to?

Hi! Thanks for your reply!
This is the link to the Isacc SimOffice Hour video:

Here they mention some Warp examples and explicitly show the particle example in more detail including the action graph (starting at 34:30).
Based on this i tried out the cloth example and tried to reconstruct it but ran into the error i mentioned above.

Please submit your issue regarding the office house through GitHub - NVIDIA/warp: A Python framework for accelerated simulation, data generation and spatial computing.? Thanks.
