I want to use Mobile HDR for bloom effects critical to my project. I have a clean install of UE5, began with the starter VR demo, Enabled ‘Mobile HDR’, added a post process volume and turned up bloom, My left eye is black. I disable MHDR, I see both eyes but no bloom. I’ve heard disabling MMV fixes this, so I uncheck MHDR, disable MMV, but still one eye broken. I have also experimented with enabling / disabling Instanced Stereo to no avail. What works for you guys and how do I make this work! Please help! ---

I’ve heard disabling MSAA fixes the black eye with mobile HDR in UE5. Give it a try. ---

This worked to resolve the left eye blank out! Unfortunately it now has caused some weird rendering effects / flicker in the left eye I haven’t seen before - but I am going to test some other AA methods and VR settings to get a full fix now. Will post a solution if i get one - otherwise this is the closest I’ve gotten. Thanks @Muscle_Kay ! ---

Hey there, have you found the fix on weird rendering/flickering that you described earlier? ---

Thank you so so much! This saved my life on UE 5.0.3 when none of the other suggestions (disabling/enabling Mobile HDR, Instanced Stereo, OpenXR plugin, MetaXR plugin)! For posterity, I switched the anti-aliasing to FXAA. Hoping someone else can explain what’s going on or if MSAA has some bugs for now because MSAA has always recommended in UE docs like this [XR Best Practices in Unreal Engine | Unreal Engine 5.0 Documentation](https://docs.unrealengine.com/5.0/en-US/xr-best-practices-in-unreal-engine/) ---

Update: Looks like Unreal has another documentation here on VR/XR features. [XR Performance Features in Unreal Engine | Unreal Engine 5.0 Documentation](https://docs.unrealengine.com/5.0/en-US/xr-performance-features-in-unreal-engine/) I tried the steps and I’m no longer getting the same issue on my Quest 2: - Enable _Mobile Multi-View_ - Disable _Instanced stereo_ - Enable MSAA Just take note that MSAA will cause some specular aliasing which will be noticeable as shimmer in VR as our camera is always moving. See this video [Robo Recall Performance Optimization | Project Spotlight | Unreal Engine - YouTube](https://youtu.be/3Yx9IEOc5s4?t=1923) for some explanation ---

Thanks for this. At the time of this post - I had to resort to using a stable version of ue4 and abandoned ue5. I’ll give this new methodology a go - but I’ve marked this as a solution for the moment. Thank you! ---

Thanks for checking back! I just found out application spacewarp is only available on 4.27 so I’m totally envying you right now though. ---

Didn’t work for me, still one eye blank. FYI ---

For anyone trying to make post-process effects work on Quest 2, I also struggled, here is conclusion: [Reddit - Dive into anything](https://www.reddit.com/r/unrealengine/comments/16278ed/infraredcamera_effect_for_quest_2_vr/) hopefully it will save you some time. ---

i can be able to make it work, but is expensive, I ACTIVATE hdri mobile, and disactivate multiview, and change to deferred shading and work in both eyes ---

@sergiogonzo > [@\_9528](#): > > Hello, is the ACTIVATE hdri mobile you mentioned referring to the use of the HDRIBackdrop plugin? Was “mobile hdr” actually misspelled? > 1.activate hdri mobile > 2.disactivate multiview > 3. Use the deferred rendering mode > > Is there anything else that needs to be revised? After modifying the test according to the above three conditions, I still found that it didn’t work properly. One eye’s rendering was completely messed up.
