I did two things just to make sure.
Unreal engine 4 light leaks from wall to another.
Directional light intensity is 5 and spotlight intensity is 1.
I tried different lightmaps with small and large padding and resolution of 1024 and no matter what i do it always has this leaking in this corner and on the top of that wall.
Leaks happen with dynamic and static lighting.
Unreal engine is the world s most open and advanced real time 3d creation tool.
I get sunlight leaks in seemingly random corners of rooms.
The ao contrast settings may be too high in the lightmass settings.
In preview build i tend to get light that leaks in corners.
I have some torches on a wall but you can see the light from the lower room space glowing up the wall even though there is a floor between them.
Also setting the light build to production lighting may fix the light leaking as well.
Leaks happen with production value lighting and a lowered static lighting level.
Continuously evolving to serve not only its original purpose as a state of the art game engine today it gives creators across industries the freedom and control to deliver cutting edge content interactive experiences and immersive virtual worlds.
This is a quick fix for the light bleed that i was having a while ago.
Sometimes point lights shine through walls to varying degrees.
One i made sure the wall was overlapping the floor and no space at all.
This solution works in other engines like unity and ue4.
Help how to solve light leaking through the wall.
It doesn t matter if the mesh uses 2 sided lighting.
They occur with static and brush meshes.
