Suddenly no materials


So I was working on some Lighting (My scene seems pretty dark), then suddenly all my door actors had no more a material on them (it did earlier) and everything is black. I did a lot of rebuilds, replacing lights and so on. but it didnt change. Except if I put a Light directly infront of it the material strangely apperas.

Thanks 4 help


The problem

How it should look


If your Door is Actor, then it can receive light only from the Stationary or the Movable lights. Check all lights and set their in Stationary mode.
