Atmospheric fog in Blender 2.8 I am a long time Blender user and I built some nice scenes with it. I also love the new 2.8 but ever since I was working with volumetrics in Blender I was never really happy with it. 

So what I want to achieve is something like this: 
A Fog, which brighten up things in the back + dont nessessarily make it muddy grey (as it always happens in Blender) 

So I know three ways of creating dusk in Blender, but none of these is really what I want.


create an Object and give it the volume-scatter material. There you can lower the densety until it gets a nice foggy feel. Unfortunately, the only result I get is stuff like this:

a muddy looking grey + dark fog. Yes I can higher the strenght of the light - but this doesent really solve it. First the rest of the scene gets way too bright and secondly there are still greyish parts in my fog. Not as in the reference picture I posted at the beginning. 


2.Create A volume scatter node in the world node editor and plug it into volume. There I get pretty much the same thing, but over my whole scene. Still not right .. 

3.Add Volumetric Fog in the composer AFTER the rendering. But this is kind a complicated to be honest. You need to figure out the exact numbers for the volume density and render over and over again. I gave up on using this technique because it was too complicated to be practical in my eyes

In game engines like Unity or Unreal I can achieve this with one or two buttons, and it looks exactly like I want it to look. 
Therefor I even found a cool gif/vid on twitter: https://twitter.com/i/status/1148767976096747526
check it out. Something like this or at least a world volume adjuster HAVE to be possible in Blender. How?! 

Kind regards

I'm sure you figured it out by now, but it took me a while to find the right answer...so for anyone else: I used the Principled volume node
At first it is also dark, but take a look at the Emission Strength and Color Parameters...the dark fogs shall lighten up for you!
Have fun!
