Lightroom: Interior Day Light Unreal 4.7.5 problem

Hi!

I downloaded this free Scene, opened, changed nothing, just hit the “Build” button, and after recalculating everithing, the result was not the same (see picture) as after the opening. Ist there really so much different when opening this Scene with Unreal Engine 4.7.5? Or am I missing something? Please help! Thank You very much!
(sorry for my English)

Sorry for the noob question. I found the solution myself.
The “Lighting Quality” should set to “Production”. For more info visit:
