Unity Particle Pack not working in XR

I incorporated the standard Particle Pack in my XR project. While in the editor the provided prefabs look fine, when deployed to Oculus Quest 3 only the 3D assets are visible (sparks, embers and debris), the actual flame and smoke is not rendered. Any ideas where to look?
My project uses URP/

Ok, so I guess I found a solution for the immediate problem - this was due to the materials used being in Transparent mode. For some reason that prevents them from rendering. Changing to Opaque with Alpha Clipping makes them sort of work. It’s ok-ish for now, but I would like to be able to use transparent materials in VR.

Googling revealed a few threads with a similar issue, but the solution there was to disable Opaque Texture in URP settings, which is already disabled in my case. So not sure what’s causing it.

You could report a bug for this via Help->Report a Bug in the Editor, and we would take a look.
Thanks for raising it!

ah, cool. I wasn’t sure if it was something with my project settings and not really a bug, so I replicated from scratch by creating a new project and importing the Particle Pack in there. Same effect. So I’ll go and submit a report. Thanks!

Setting “Use Depth texture” true in URP fixed it for me

“Use Depth Texture = True” didn’t fix it for me.
I did get it working, by going to my URP_Asset_Renderer and setting “Depth Texture Mode [FORCE PREPASS]” and setting my renderer to Vulkan.

The particles now are visible.

Might I just add, my VR project was using the Built-In renderer, and all my particles worked nicely. I now have an asset I need to use that required URP, so I upgraded my project. I was under the belief that URP was supposed to be more performant, but the particles, once I got them all working again, are now causing serious frame drops. I gotten my project working fluidly and solidly at 72fps before. But in URP I’m not getting that.

I may abandon this new asset and restore my project back to built-in renderer from version control. I had no problems with anything inside Built-in renderer. Clearly I don’t know what I’m doing with URP. I think I’ve set everything to a similar or the same quality, but it’s not happy.
