I have same issue. There is guide for which effects are supported. I tried vignetteintensity, which is listed as supported, but effect happens just on left eye, right eye is completely blank.

This is the guide: [Post Process Effects on Mobile Platforms | Unreal Engine 4.27 Documentation](https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/Mobile/PostProcessEffects/)

I guess solution is here: [Quest 2 Mobile HDR - left eye black / not rendering - #5 by roushenzo](https://forums.unrealengine.com/t/quest-2-mobile-hdr-left-eye-black-not-rendering/615972/5)
