[BEGINNER] The lights don't bounce

Hello, I am a beginner on UE4 and I have a problem. When I look at the house in the preview scene, the lights are perfectly well managed. But in the level, the light does not bounce, which gives a result with unlit areas. I have tried many things but nothing helps.

Thank you in advance for your solutions :slight_smile:

In the preview scene:

In the level:

You appear to be using dynamic shadows. Dynamic shadows will only have ssgi to help out with bounce light, go with a dynamic skylight, or, wait till unreal 5 in 2021
