Okay,
i found it and it works to 50%.
The "class reflectors" works and blind me, when i look into the light. When i'm under the lampe, i see my character illuminated. But on the floor / wall i see no lights! Objects i put into the building with proxy are illuminated too.
WHEN i move the object in the editor under a lamp, which is orginallys on map, i can see the light on my floors.
Class MarkerLights
shining through the walls. The walls outside are shining like a sun... :D
I try to switch to "Class CargoLights", and then everything is dark.
Can somebody help me?
