Godot XR: Pico 4 Export Broken?

Godot Version

Godot Version 4.6.3
Godot XR Tools 4.5.0
Godot OpenXR Vendors Plugin 5.1.0

Question

I created a new project and used ProjectToolsXR Project Setup (which is very cool, btw. :blue_heart:) to setup everything (XR Mode = OpenXR, Grade Build, Pico Plugin enabled etc.).

Exporting works, the build shows no errors.

But after installation and start on the Pico 4 the app crashes immediately. This worked for Godot 4.6.2, so maybe it’s a bug introduced in the newest version?

Has anyone else seen this problem? Or am i the only one using a Pico 4 (NOT Ultra!) now and then. :upside_down_face:

This is a known issue in PICO OS.

We recently added support for the XR_META_foveation_eye_tracked extension that the PICO runtime also supports. Unfortunately seeing the PICO 4 (Ultra) doesn’t have an eye tracker, it causes a crash. It will be fixed in an upcoming release of PICO OS.

We did make a fix in Godot so you can disable support but it’s in 4.7. You can read more about the issue here:
