You can use the volume fog like listed in the tutorial above or you could always take the z-depth pass and screen it over your scene and mess around with it until it looks good

Hey,

Thanks that was usefull.

However, in the video he's reffering to the "scale" option which I don't have.
It's turn out I'm just having constant fog, no matter how close or how far the object is

I have the same problem. I think in 2.25+ they had the scale option (or an early alpha of v3) and maybe didnt put it back in. The fog settings are messy imo and should be redone in a better way :/

Hi,
the Scale value was renamed in Density some version ago, while the Thickness value refers to the Medium radius value and must be setted based on the scene dimensions.

Hey man,

Thanks for your reply.

I've been messing with both thickness and density this whole week and I couldn't find any paramters that actually emulate the atmospheric fog I'm looking for. Everything looks like there is a permanent fog with the same density everywhere, we can't feel the deepness at all, whatever the parameters. I'm using a 500 meters box with randomly placed boxes to test it.

I'm looking to create something similar to this, where you can feel a close object and a distant object :

Any help would be greatly appreciated :)
Thanks !

I also didn't succeed to achieve the right effect with the environment medium fog.

I'd love to see a scene when the fog become dense when looking to the horizon.
