Quest 2 - Android Vulkan
Mobile HDR = OFF
At some point I must have touched a setting that drops the brightness of the game in VR when playing through the editor. The resulting colors don’t match the Vulkan preview mode in the editor itself (which washes out towards a middle gray), or the standard SM5 colors when that mode is disabled. It’s just darker, with heavier shadows as if the exposure has been dropped, but only for VR.
The problem doesn’t appear in builds either, so it’s either related to PIE or to PCVR (since Quest 2 behaves as a Rift when connected to PC).
The only post processing volume in the map is part of Ultra Dynamic Sky, and the problem persists when that is deleted entirely.
