Working on a new environment and I'm just testing out lighting atm. However, I've run into a weird lighting issue.
As you can see in the following screenshots, light is bleeding through in very strange locations. I'm getting lighting leaking through the exterior walls, and it seems to be bouncing incorrectly. The exterior house is being lit by lightmass, but the only orange light in the scene is inside the house. I don't know how this is happening!
I'm also using a dominant directional light and a skylight, but they are set to very low blue colours.
Let me know if you have any ideas on how to fix this issue, it's very odd.
I've tried using gigantic lightmap resolutions, but still getting the bleeding issue. Even with a relatively low lightmap res, it shouldn't bleed this much, and the exterior shouldn't be lit up.
EDIT - It's fixed now. For some reason, 'enable shadow casting' was turned off on all my static meshes in the generic browser. Strange.
