Set the entity type to MoveObject or possibly Object > Static.

You can edit the fog properties of how thick it should be. Play around with the settings. Also, make sure to set a skybox, because empty skies start to glitch with fog.

Huh?
Skyboxes also look weird if you use fog. Fog doesn't work on a skybox, so only everything else will be fog-ified.

If you use the domes that CarnivorousJellybean made, which are actual objects, then the fog will work.
