What folder i must use get get it work?

P.S.

I think environments not included in 72 version, as it was in 71, because size of 72v 38Mb, and 71v 184Mb.

In 72v missing folders

- ses_rooms~

- .synth_env_server

- .local_sharing_server

and few others.

How to start XR Simulator v 72?

These are the steps I have in my guide, all works ok here.

Meta XR Simulator

1. Unzip "meta_xr_simulator_v72.zip" file to "C:\Users\name\Documents\Unreal Projects"
2. Uncompress the .tgz file within the "meta_xr_simulator_v72" folder
3. Set the "Meta XR Simulator JSON file" location in the Meta XR plugin: C:/Users/name/Documents/Unreal Projects/meta_xr_simulator_v72/com.meta.xr.simulator/package/MetaXRSimulator/meta_openxr_simulator.json
4. Close the Project Settings window
6. File/Save All
5. On the VRTemplateMap Tab locate the "Meta XR Simulator" menu
6. Open it

You're correct, I have just redone everything, and the rooms are no longer showing under "Meta XR Simulator/Synthetic Environment Server". I also noticed a "Meta XR Synthetic Environments" path in the Meta XR Plugin, but I'm not sure where it should point to (I tried lots of random locations).

It looks like the rooms are missing from v72 (as you noted), and v71 doesn't seem too thrilled about UE5.5.0. Perhaps Meta needs to work some magic, or we could be missing something.

Worked for me with Meta XR Synthetic Environments path set to [yourfullpath]/package/MetaXRSimulator/

Of course we should be born with this knowledge.

When setting the path to the MetaXRSimulator folder, I no longer see room listings as I did before. Maybe this has changed? I rarely use the simulator, so I may not be the best reference.
