God rays through a glass panel?

I'm trying to some god rays using light that's going through glass. Although I'm using a light portal and some volumetrics, they still don't show up. Any ideas?

Disable Opaque for the glass.

I have that disabled. It's still not appearing for some reason.

Why are you using a Light Portal with Atmosphere Volume?

Its hard to tell from this render, but isn't there some faint Atmosphere Volume here? Try increasing the Density of the Atmosphere Volume or the exposure of the scene lighting.

Hmm, I tried increasing the density and I disabled the portal lights, no luck still 😕 Can you maybe take a look at the scene if you have time?

Sure, can you simplify it first.
