Level Design Strange lighting

[Foo'bar]

Recently I was playing around with dark rooms and now I have strange behaviour with lighting. When driving with vehicles into a zone with less light than the surrounding zone only the turrets will be darkened (like on image):

On players only the helmets and the field gear will be darkened, clothes and skin stays bright.

Anyone?

I expierenced strange lighting as a symptome of a Hall of Mirror effect. Which means find the brush which is causing it and delete it :/

As soon a player is sitting inside a Halftrack located inside a dark zone all player's surface is correctly darkened
