Passthrough

Only available in versions 1.1.1 and later of the OpenXR plugin.

Passthrough is a new feature introduced on the Meta Quest and added to the OpenXR spec as a Meta extension. It is likely this implementation will be implemented by other vendors where the hardware supports a passthrough mode and promoted to core at some point.

If you are using the scene, you can simply enable passthrough by checking the Start Passthrough option on the controller node:

Note

The Viewport’s Transparent Bg property must be enabled prior to starting passthrough. The plugin will log a warning message if it detects an incorrect configuration.

A fix for a bug related to turning transparent background on/off is scheduled for the Godot 3.4.3 release. If you wish to toggle passthrough in your game, you will need to be on that version or newer.
