Falloff map for BoxLights?

[Tomlacko]

Hi, in my custom story, I'm trying to have a well-lit area (using a box light) and some dark tunnels with no ambient light. The problem is the border between the lit and dark area. I tried using the falloff map option on the BoxLight (and on other box lights to test it) and it just doesn't work, I also checked in-game to make sure.

So I'd like to ask, do falloff maps not work for box lights at all? And if so, what can I do to make a transition between the two environments?

So I came up with my own solution, which is just having two script areas, one of which will fade the light to darkness and the other will fade it back. This way the transition works perfectly, but it still would be nice, if falloff maps could be used for BoxLights.
