when I open the lighting, the world becomes white, I can’t sen anything。
The effect of lighting on and off is completely different
Hello @irvin, welcome to the community.
By default, the intensity of CesiumSunSky is set very high, to match real-world light sources. Sometimes, this can cause issues with the auto-exposure. If you don’t require geospatially accurate lighting, or you simply want to keep exposure in a more standard range for game experiences, select CesiumSunSky. In the details panel, select the Directional Light component and set the intensity of the light to 1.
Or you may prefer to add a Post Process Volume and adjust the auto exposure. You can read more about that here - Auto Exposure (Eye Adaptation) | Unreal Engine Documentation
