Icons under objects "O"

Im new to GMod.
I would like to know how do I disable these “O” icons under some objects like trees, grass, etc
I tried cl_drawhud 0 etc it didnt help

Is it a green ‘o’? if so then the thing you spawned is an effect in which case the o is what you use to move the effect. Or Something…

They only show up when you have the Phys gun out I believe. They are only there so that they can show you where to shoot to move it. Just switch weapons.

Yes, but I want to use phys gun while having this objects on map

Well, unless you hunt down the texture for it, you’re stuck with it.
