OCEANSIM not appearing inside IsaacSim Extensions Window

[sotomotocross]

I have followed all the installation and setup instructions and when I opened the Isaac Sim GUI and navigated to the Extensions window nothing was there regarding the OCEANSIM as indicated.
What's the problem here?

Hi,

Thank you for using OceanSim,

If possible, can you provide the folder structure to the place where you cloned the repo.

This is the output of tree -L 2 from inside the folder I initially installed IsaacSim and later the OceanSim and OceanSim_assets:

I have run cd /path/to/OceanSim python3 config/register_asset_path.py /path/to/OceanSim_assets in this folder, I launched the IsaacSim GUI and tried to insert OCEANSIM as indicated but nothing was appeared as I told you.

This is the Extensions Window that opens with the Isaac Full App when it's loaded.

If you are installing Isaac Sim from source, OceanSim may not appear in the Extensions window even after cloning it into extsUser. When using a source build, Isaac Sim does not automatically scan the /extsUser directory. We need to manually add the extension path in the Kit configuration file.

open the Isaac Sim kit file located under

_build/linux-x86_64/release/apps/

Find the file named isaacsim.exp.full.kit

Inside that file, locate the section for extension folders and add your extsUser path like this

folders = [
"${app}/../exts",
"/home/your_username/isaacsim/extsUser"
]

Make sure you use the full absolute path instead of using ~.

After saving the file, clear the cache if needed and restart Isaac Sim. OceanSim should then appear in the Extensions window after removing the @feature filter.
