Some info: - Mobile MSAA set to 4x - Bloom ON - Instanced stereo OFF - Mobile HDR ON - MMV off - Vulkan ON - Building for 64 bit - Project made in blueprint I understand there’s a performance drop for using Bloom - but my app that I’m trying to run is literally a menu with a skybox and a few particles. I’ve seen plenty of UE4 production builds of apps run with bloom which really enhances the visuals - as sun discs, point lights, emissive materials all give off that nice glow. The error I’m currently running into is: The only way I can get a nice bloom effect working is by enabling Mobile HDR, but when I do - only one half of each eye is rendering… So if I close my RIGHT eye and view through my left, the left hand side is a still frame of my experience, the right hand side is functional. And if i close my LEFT eye, the same exact thing happens. So it’s not simply breaking one of the eye’s its actually only rendering half of each… **A: Has anyone run into this sort of thing before and knows a fix? B: Is there another way to get nice bloom going on emissive materials etc rather than enabling Mobile HDR?** Here’s a screenshot of where the left hand side is a still frame of the scene that is locked to the HMD, and the right hand side moves dynamically with my head movement. ![353653-ue4-answer.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/c/4/a/c4a92e84c0bcf597e07f39e2002b37c5f4d16652.png) ---

I have the same issues now, and I think the bloom effect is essential for mobile VR for some art directions. ---

Hi Cakezilla, there’s other people experiencing the same issue, we’re discussing it on Discord: > **[Discord - A New Way to Chat with Friends & Communities](https://discord.com/channels/415153324099371008/765200535628152833/917733483051360296)** > > Discord is the easiest way to communicate over voice, video, and text.

you should also disable Vertex Fogging For Opaque
