Hello I have this problem!
I’m using white planes for lighting up my interior like the one in this tutorial : https://www.unrealengine.com/blog/simulating-area-lights-in-ue4
The interior gets all the light right, but the exterior looks horrible! I tried checking and unchecking different settings but the only way to fix it is disabling the spotlight’s attenuation radius. If I disable this, the light in the interior gets a lot darker and bad.
Is there any other way to fix this? Even if I disable visibility of the planes looks bad
The red floor has a lightmap resolution of 1024 so I think its enough, but light looks sooo pixelated!
Here are the screenshots of my settings
This is the plane :
And this is the spotlight :
