Volumetric lighting in Eevee goes through mesh I created a fog in my scene to get the beam of my light in Eevee. I deactivated the shadow produced by the lustre mesh so as not to break my lighting. This option active or not, my light passes through my mesh. Do you have any idea where this might come from?
In eevee go to your volumetrics tab and crank up samples and light clamp.
