Hi

I’m not sure if I’m missing a simple tick or if this is an actual issue

after inserting height fog, my bottom half of environment is still black, even after turning all the scattering colors way up. never encountered this before

so for anyone that MIGHT run into this as well, YES, it is just a tik lol.

If you are doing physical based values; directional light,m skylight and etc… you need to crank up the heigh fog value as well.  
automatically, it is bound to between 0-1

how to: where you select the _ **fog inscattering color** _ to bump up the value from 0 (black) to 1 (white/visible) so you can actually see your fog. that value slide is bound to 0-1. underneath, select the V (Value) and input a mad number: (200-400) what-ever you deem good for your project.
