My Walls have light entering the edges
Hi im having a problem with lighting. My project is an architectural visualisation and i have separated walls into different groups in order to get maximum quality out of the lightmaps.
I have an issue with the lighting as the light seems to go through my walls and bleed from the edges. My build is on production and my walls lightmap sizes are 512x512 and the floor is 1024x1024. I have let unreal engine 4.5 generate the lightmaps for me.
I have used a spotlight from the exterior to represent the sun and a plane for it to reflect on, just like the market place content "xoio Berlin Flat". Is the problem that my floor and wall are not 100% in the right place and not connecting? or my UV mapping is bad?
I have provided images of what i have explained above and also the problem, id like to thank you in advance for taking the time to reply.

Can you try building the lighting in Production mode if you've not already done so? Preview and any mode lower than Production can generate the light bleed you're seeing, in most cases. If that doesn't solve the issue then it may be that you need to revisit your lightmaps and set the hard edges to snap on the grid in the UV space for your hard edges. The grid will need to be set up to the lightmap resolution you're targeting.
You can find more information about lightmaps here in this forum thread. There is a lot of information being discussed that can be helpful. https://forums.unrealengine.com/showthread.php?46269-Modular-Asset-Lighting-Problem
