Switch between different lightmaps
How to have a level with two different lighting conditions (different position of sun to emulate two different day time), and build lightmaps for both lighting conditions, and switch between them in the Editor to see the light effect and compare both them?

Hey janherca -
In order to do this with static lighting you would have to have your level built (level A) with Morning lighting as a non-persistent level then duplicate the entire level and save as level B. In level B, add, remove or change lighting to reproduce the evening lighting. In your persistent level blueprint you can then set up a Blueprint load for each level independent and you can switch between the two levels.
I have attached a sample setup for this Streaming Process. The important thing is to rebuild lighting for each sub level with the other turned off and just acknowledge the warnings but continue to build.

For anyone reading this 4.14 introduced the "Lighting Scenario" feature enabling you to stream in different light map bakes for the same level. https://answers.unrealengine.com/questions/512084/who-can-explain-of-lighting-scenario-feature.html
