I have a facility map split up into several sub levels using level streaming volumes to load/unload spaces as needed. The main issue I’m having, is when I put an exponential height fog in the persistent level (or even in any sub level) with volumetric fog enabled, it only seems to work in 1 level not all of them and changing what level the fog is in does not change the level the fog is working in. How do I get the fog to show up in all sub levels?

At the moment I’m having a similar issue where the fog shows up in the sub-level (if I open the sublevel separately), but when the sublevel is active in the Persistent Level, there is no fog.

EDIT: Just learned that you can only have ONE Exponential Height Fog in a level. So, if you want a localized fog effect, well, use the localized fog.
