I've been reading a lot about this, but I can't find the solution. Anything I've tried so far hasn't helped at all to solve my problem.

The scene is simple. There's a sun light outside which is blueish because this is gonna be a night time scene. I need a volumetric (god-ray like) light coming through the window. In the screenshots you can see my settings.

In order to use the sun light for this, I created a box that surrounds my scene and I've made the volume scatter material for it. I read that .1 is a good place to start at, but it makes my scene completely black. If I get to .001 I can see but I don't really think it creates any volumetric light.

I tried both a 1cm sun and a 1m sun, but nothing changes. sun strength at 50,000. I tried even more nothing changes and it seems stupid for me that I have to go higher to make this work, because I 've seen a lot of people working with much less and it works just fine.

Any help would be appreciated.
