Empty folders and can't activate the addon

[CarrascosaArnaud]

When I DL the addon, then install it, it only gives empty folders with only 3 files in total, and I can't activate the addon in the project settings.
I've tried to delete it and download it many times, restarted Godot and my PC aswell, nothing is working. I use the latest stable Godot version 4.3

With the latest version, there's nothing to enable in project settings, although, in Godot 4.3 or below you will need to restart the editor after copying the files in.

The files are there, but they won't appear in the Godot editor. If you look with your OS file manager you should see them (if you're on Linux or MacOS, you'll have to enable showing hidden files, because they are stashed in a .bin directory).

One way to check if the plugin is loaded, is to search the help for one of the classes provided by this plugin, for example OpenXRFbSceneManager:

Ok I see, the plugin is inee loaded then, thak you for your quick answer. I was following this tutorial : https://www.youtube.com/watch?v=BrNZs4XzU0w&lc=UgwnQXtRe5mMiMv_0yZ4AaABAg.AEUzLxJIlpUAEVDuEFDpp2 , and it seems the plugins has totally changed since then, even if its only 1 month old

I skimmed through that tutorial and I have one note:

• They recommended using the "Mobile" renderer for Quest - in fact, we recommend using "Compatibility" for Quest or any Android-based devices (reference in the docs):
  

Other than that, that seems like a pretty good tutorial :-)

The official docs are in the process of being updated, which still show installing the 2.x version of the addon (which does require enabling in "Project Settings"), whereas the 3.x version does not.
