Hi @H4x03D , did you get this resolved? I just tested again in UE5.2 and I still get the same crashing behaviour. Seems like it’s either a deeply entrenched issue, it only happens on upgraded projects or nobody is using planar reflections in VR… I expect the last two cases are uncommon situations. I’m hoping you were able to make some progress?
EDIT: Just to be absolutely certain, I created a new VR project in UE5.2 and added a planar reflection. I did not make any other changes to the VR template instance. Pressing play in VR from the editor crashed the game with the same error:
Assertion failed: ViewIndex != INDEX_NONE [File:D:\build++UE5\Sync\Engine\Plugins\Runtime\OpenXR\Source\OpenXRHMD\Private\OpenXRHMD.cpp] [Line: 3821]
Looks like this is a bug in the OpenXR HMD driver.
