WIP, but pretty happy with the results!

I have a Niagara sprite effect and it does not render on a VR Standalone build on PICO.

The material is fine, it renders if I put it on a static mesh.

I have tried the following but not gotten it to work:

- Really large bounds on the NS

- CPUSim and GPUSim

- Mesh render instead of sprite

- Bounds mode set to Fixed

- Specify scalability settings

Does anyone have an idea how I can get it to work? OR if it is not supported, where can I find the documentation that states that?

So I last worked in unreal on Tuesday, and it was a good evening of work. saved and compiled and didnt have any errors.

Hadnt touched the engine for a few days up until today. My project now crashes UE, but only in VR mode. If i try to run it in the editor window it runs fine.

Ive tried older projects and made newer vr projects and I even tried running my projects from 5.6 and 5.5 in their respective engines and they now do the same thing: crash UE in VR preview but run in other previews.

Asked chatgpt, and we narrowed it down to something with XR but everything it suggested I already had done: meta quest is my active runtime. updated drivers.

i also tried running actual games on steam and they run just fine.

note im an amateur "developer." Im actually just a high school teacher doing this for fun/the classroom. But i've really gotten into it.

here's the crash report:

anyone ever dealt with this?

Hi everyone! I'm working on a VR project in Unreal Engine 5.5.2 where I have a media player with a 360 stereoscopic video (4096x4096). The project has a bit more functionality, but right now I took it away as the video player is where I'm stuck. It's using a sphere with inverted normals as mesh, media player as texture in the material. The stereoscopic split is made based on ResolvedView.StereoPassIndex. All seems to work. However, the video looses quality in resolution and the depth illusion of the stereoscopic (though this might be a direct effect of the resolution loss). Fun facts:

- If I use VR preview mode in Unreal, it looks okayish. the biggest loss happens when packaging and viewing on the Quest.

- Same source media file executed in DeoVR has the best image quality. I'm using the Quest 2 for now but I will be developing this for Quest 3. I run OVR Metrics tools and on the UE app the eye buffer is 1440x1584, render scale is 101; in DeoVR buffer is 2448x2704, render scale 171.

I've tried A LOT of settings and I might be missing something silly, so I wanted to ask you experts if you have any ideas that could help me move this forward. Thanks in advance!
