Hello

I see that light function material doesn’t effect the exponential fog .
is there any setting or material maybe that I need to tweak?

thank you in advance

Play with “Volumetric Scattering” of your light source. Also the Fog needs to have “Volumetric Fog” enabled.

I can’t see your gif but I ran into a similar issue recently. Turns out I had “Fog Density” scaled way too high, and that was killing the light off before it reached my camera.
