With PIDI Planar Reflections 6 we have added support for VR devices but in an experimental fashion. This means that no specific devices are officially supported, bugs may not be fully solvable and the feature has not been tested on-device, so you will need to use it at your own risk.
It has been thoroughly tested in simulation mode with different plugin providers such as Open VR, Mock HMD, Meta’s Quest simulator, etc. and in all tests it provided accurate reflections. There is no additional setup you need nor any settings to modify, reflections will automatically adapt and adjust when you set any of your cameras to be a stereo-enabled camera and the corresponding Unity.XR modules are enabled.
VR support works on both the Universal and the Legacy Rendering Pipeline and is tailored for Single-pass stereo rendering. It may be compatible with Multi-pass in the Legacy Pipeline, but this has not been thoroughly tested so Single-pass instanced is the recommended way to use VR reflections.
