VFX doesn't show anything in the simulator or headset

I’ve an issue with a VFX made with ShaderGraph (URP) which displays well on the editor and display nothing in the simulator (or the headset). It’s composed by a mesh which use a custom LIT shader, and some particle systems attached to it which also use custom LIT shaders.

It seems that disabling the Alpha makes the FX to display. So my understanding is that the Alpha chanel is not supported in VisionOS right?

Hello! Alpha blending should be supported. If you can submit a bug report with a repro case and let us know the incident number (IN-#####), we can attempt to debug.

If you’re using a default Unity particle system and have the option Replicate Properties set that will create a realitykit particle system which does not support custom shaders.

I tried using the other option that bakes the PS but it doesn’t work too. I’ll open an issue and report the number here.
