Display beam on top of part

is there any way to display a beam on top of a part without changing the zoffset? changing it makes the beam move weirdly along with the camera and i want it to stay in place

What exactly do you mean on top of? Do you mean like it always visible and it isn’t blocked by the part or you want the beam to go on top of the part.

i want it to be visible and not blocked by the part when its inside it, like changing the zindex of a particle emitter

No, that’s unfortunately not possible but what are you doing to need a beam to be on top of a part for?
