Directional Light problem

Hello i have a problem with the directional light, when i launch the game the lights are built correctly but when i play it in the view something goes wrong( I didn’t create the lightmass volume, but this happened after i tryed to do that)

Do i have to set engine scalability to epic?

Hi JoyGameItalia -

Typically to get an accurate reproduction of the game envrionment in the Editor you will need to set the Scalability to Epic otherwise some Post Process elements and Texture items are sacrificed for a better performance on level editing.

Thank You
