Quest3: Virtual Window/Portal through passthrough into a virtual world

Hello everyone,

We’re struggling to get a “window/portal into a virtual world through passthrough” effect working on the Quest 3 with the latest Meta Plugin (v62) and Unreal Engine 5.3.2

  • There does not seem to be a working “inverse” material that punches a hole through an overlay passthrough layer, which would be basically ideal.
  • Alternatively, I tried to use an underlay passthrough layer and get a regular portal effect via custom depth & stencils, but that just does absolutely weird things when deploying on the Quest itself, I assume because post processing / mobile deferred rendering is really not well supported.

Does anyone have any other pointers into what could work? I kind of just want my real window/door look out into a virtual word. We’d be really thankful for any help!
