【Bug】Isaac Sim extension cache not recognized — OmniGibson still tries to download extensions online

[may210297]

Describe the bug
I have already downloaded and installed the Isaac Sim extension cache packages (isaacsim-extscache-physics, isaacsim-extscache-kit, isaacsim-extscache-kit-sdk) during executing ./install.sh --bbdl --omnigibson --dataset. However, when initializing OmniGibson, the system still attempts to fetch extensions from the Omniverse registry. Since my server does not have internet access for these registries, the initialization fails.

I tried to annotate the following lines, but it does not work.

BEHAVIOR-1K/OmniGibson/omnigibson/omnigibson_4_5_0.kit

Line 37 in 7109169

registries = [

Desktop (please complete the following information):

• OS: [Linux-5.4.0-generic-x86_64-with-glibc2.36]
• isaacsim: [4.5.0]
• Omnigibson [3.7.1]

Aditional Context
Is there a way to force Isaac Sim/OmniGibson to only use the local extension cache without connecting to the registry? For example, should I configure specific environment variables or adjust settings to ensure it runs fully offline?
