Hrm. So, the hands don't move or react at all?

I'm using the default OpenXR Action Map from Godot 4.7, and it has a "Pico 4 controller" profile in there, which works fine on my Pico 4 Ultra

I'm assuming controllers work fine for you when running your own games using Godot 4.7 on your Pico 4? If you run any Godot OpenXR app on your Pico 4 with verbose output turned on, it'll print out all the OpenXR extensions it can see, and I'd be very curious to see what's in the list. The thought I'm having is that maybe older Pico 4's don't have the `XR_BD_controller_interaction` extension?

The WebXR version, tested, works. I tested only the Pico (APK)-version yesterday.

I'd still love to debug why the APK doesn't work! If you have a chance to try any Godot game with verbose output turned on to list the extensions, that'd be great. Or, at least seeing if vanilla Godot 4.7 works, and if not, the last Godot version that did work

Tested a clean project in Godot 4.7.1 stable (Linux). Godot OpenXR Vendors PIugin v5 loaded in asset store. But no vendors-list shows up in Export, Android under OpenXR-select tab. Same with Vendors PIugin v4

Mobile renderer crashes on Pico4, gI_compatibility loads forever like no standalone vendors loaded.

By the way Balloon Dino Death Dome by Kimau Pico4.apk worked.

Downgraded my simple 4.7-project, tested with v4.5.1 and Godot OpenXR Vendors plugin v3: Works. Tested with 4.7.1 and vendors V3: works, but hands (MeshInstances3D boxes) don't move.

Hrm, some very odd results. The v4 and v5 versions of the vendors plugin should definitely work in the editor with Godot 4.7 on Linux... (I built my project with v5 and 4.7 on Linux!) It does sound like there could have been a bug introduced in Godot 4.6 or 4.7 that broke things.

I wish I had access to an original Pico 4, but I've only got the Pico 4 Ultra, and, unfortunately, Pico headsets can't easily be purchased in my country :-(

Tested Godot 4.6.3 with v3 now: The hands are not reacting on it. so it's not only 4.7.

Anyway, maybe we wait for others with Pico4...
