Light bleeding on edges

[whitwhoa]

Not sure if this is something that would be related to this plugin specifically, blender in general, or perhaps how I'm modeling. I appear to be getting a lot of light bleed happening at the intersections between different geometry. I have provided a screenshot below that should make clear what I'm attempting to describe. It is of a floor plane, a wall plane, and an archway object all intersecting each other and the light bleed that is occurring. This also appears to be occurring on any geometry that's not water tight.

Would there happen to be a setting somewhere that could be used to lesson this effect?

OK, so after further analysis I have corrected this. It was for sure on my end. I had a world light that was applying lighting from the exterior, which I did away with. I also had several lights that were clipping past where they should have, which is where the bleeding was coming from on the archway in the photo. Also, I increased the lightmap resolution to 512 (was 256) and set the quality to production. Results are now closer to what I was expecting :)
