Hello guys,I start following the tutorials from the Unreal Youtube Channel about how to make an environment, and I don’t understand why the light doesnt come through the windows and why the quality is so so bad.!
Set your quality settings to “epic” → under the quick settings 
+ is there a light in the level which points into the direction of the window? (e.g a directional light which points at the windows) - also make sure to rebuild your light
yes there is a directional light.
I will try
Have you set your screen percentage somewhere? This looks like scaling artifacts to me
wow it’s working with the quality, but the light is still not showing
