Foggy scene with god rays

[Anonymous]

Hi guys, 

I'm practicing with Arnold render in Maya 2019, I was trying to get the god rays effecs, but I can see the rays only in one direction and not in the others why?

What I want is a foggy scene, where a light comes out from a pierced sphere producing the god rays all around.

I used an area light, because the maya spot light get me a lot of trouble, when the fog or atmospherevolume is add to the scene the spot light makes the ray, but in the scene there's no more fog..😥

That  is the correct behavior for an area light. Use a correct light for this effect.
