Hello all! How would I achieve this effect with Exponential Height Fog? Is this possible with a Post Process effect? If so, how would I
I dont think so. You’ll have to use particles as demonstrated in the video.
No, both are Particle Systems. The engine fog doesn’t respond to light really, even though it may appear that way. You could experiment with your own shader applied to every object in your scene, and masked in by world space. It wouldn’t look great though.
Just use a particle for the fog instead!
Hey guys! Thanks for the replies. I’ll try to use a particle system for the fog, but the thing is I need it to cover a 2017x2017 landscape filled with trees. I am also using Exponential Height Fog to hide instance popups (culling) from the player. Any idea on how I would do this without murdering the performance lol? Should I create a particle system and have it move with the player? Thank you! 
That’s an option. Also dont forget to enable light shafts for the directional light. Now that you mention trees it will help with visuals when you are inside the forest.
