Collision with depth buffer

Hi everybody !

I need help, I haven’t used VFX-graph much so far, I want to enable “collision with depth buffer” in VFX-graph, for some reason the particles keep hitting the screen in Scene/Game view. What could be the reason for this?

Thanks in advance!

Hitting the screen as in colliding with the camera?
Which Unity version?

Version:
2022.3.8f1
HDRP 14.0.8

In the meantime, it has already been revealed that the problem occurs when the output Blend Mode is set to Opaque, it works fine in the case of Alpha

If the docs dont mention that make a bug report

Hi! Depth collisions are not working with particle writing depth at the moment. We don’t have a split resolve of the depth buffer in order to not have particles in the depth buffer used for collisions. As a consequence, opaque particles are colliding with themselves which makes them push towards the near camera plane.

An explicit warning is being added in the graph when this setup happens but we have no plan to fix this at the moment and depth collisions are reserved for particles not writing depth
