Hi y’all,

So I looked on this page:

Ive selected it in the Class Viewer and Right-clicked in the world to Add Exponential Height Fog. Im assuming the “world” is within the Viewer, but I dont see an option for adding the fog.

Just drag and drop either from the Class viewer or Modes Tab > Visual Effects to the level.
