4.16 Volumetric Fog, how to limit fog to a certain area?

The issue with your solution AE_3DFX is that placing an extra fog ball doesnt remove the fog from the rest of the map that “exponential height fog” causes. I’m trying to figure this out myself now, im trying to use volumetric fog particles to create an inexpesive volumetric “space nebula” effect a player can fly through, but i only want the fog from the particle, not the rest of the exponential height component. While the settings on the exponential height fog component let me minimize the world effect, i cant disable it completely or enough to be satisfactory while still keeping particle fog volumes.
