Rendering on top of GUI

Hi,

I’m looking for the easiest way to render a particle effect on top of the gui control.

I tried shader with ZTest = Always and tag “Queue”=“Overlay+1” for the particles, but it seams, that GUI is rendered still as a last object.

Do you have any thoughts how to achieve this, without using additional cameras and rendering to texture?

you can’t

GUI is the last thing and is actually rendered after the whole scene was already rendered.
