I'm setting up a large scale space scene, and trying to get some volumetric lights - like god rays. However when scaling up the volume cube, to sizes like 10,000 units the god rays disapear. I can only see either black volume, completely opaque or nothing, depending on the density. My light strength is already set to infinity.
I have a setup, with a spotlight, which works fine with cube of around 100 units size, but it's not working when scaled up ever 10x.
Any ideas ?
