    Hey there, in the course of working on a prototype recently, I've discovered that having shadow-casting particles on Oculus Quest tend to cause a hard crash on the device (using URP/Vulkan). Using OpenGL ES isn't really an option for me because of another significant bug.

    Seems like the crash will occur faster when there are more particles or bigger particles (fill-rate related?), but with a more modest particle system, it doesn't happen right away or directly in response to anything in particular... seems like some kind of accumulated effect. I tried lowering the shadow map resolution to the lowest available setting, but that doesn't seem to help either.

    Is this a known issue? Anyone else come across this? Solutions?

    Hello Aaron. Could file a bug with a minimal repro project so that we can check and fix it quickly?
