    point light and shadow casting

    Hi. I am new to UE, but so far I love it. I have used other game making software, but UE so far seems to be what I have been looking for.
    However, I am running into a few snags. I am working on a 3rd person project and learning how to add meshes and materials of my own making, but I am having an issue with the point lights doing weird things. In the first picture, the point light is doing basically what I want it to do, but in the second pic, it seems almost to be projecting light in a particular direction and not in all directions like it should, and it is not lighting the mesh right. The "ceiling" and the point lights in both of these areas are in exactly the same Z position, and the meshes are basically the same, just simple cube meshes with the normal facing inward. I have four different meshes for my walls, and they all use the same material. They all are made of a floor, ceiling and whatever wall parts I need to make the parts for the level - a line (floor, ceiling, left wall and right wall), a corner (floor, ceiling, left wall, front wall), a "T" (floor, ceiling, and only one wall), and an "open" which is only a floor and ceiling with no walls. I can pretty much make the whole level with these 4 pieces simply by placing them and rotating them as needed. I noticed that the point light only does this on the "T" mesh and the "open" mesh. I have rechecked and reimported them more than once (I'm using Blender 2.56), but always the same result.

    Next issue: The floor looks seamless everywhere till I get to a turn, whether at a corner or a T, then it looks very un-seamless (see 3rd pic). I made the floor texture completely tileable so that no matter how it is positioned or rotated it appears seamless against adjacent floor parts, and again, I have shadow-casting disabled for all of the meshes. They look fine till I get to a spot where a mesh was rotated. What's up with that?

    Lastly, I notice as I run through the level in play mode, that when I round a corner, I see flashes of light that disappear as I continue running. Is light leaking through my meshes where they are joined because there is a gap between them? I could not take a screen shot of this because it only lasts for 1 frame and I am not quite that quick,
