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!
