I am using a meshes from Unreal demos, so UV’s should be right.
I think I found a sollution. The problem is eye adaption. So i set a post processing volume and auto exposure → min brightness to 2 (max brightness to 1 but I unchecked this because my character blue body is too shiny). Also in World Settings I set diffuse boost do 2.5.
Screenes:

Play as standalone game: http://puu.sh/b7RNT/2fcf615d88.jpg
So its probably this. Is there a possibility to dissable eye adaption without the post processing volume? Or I just should make one big volume with this auto exposure settings?
