i didn't get this statement "encompas your level with a builder brush" can you try in simple please

i made map in which i have terrain 32X32 and some static meshes and one Dominant Directional Light Moveable, thats all

[tegleg]

the red cube is the builder brush
make it big enough to fit your level inside
then add the lightmassimportancevolume
its a volume that tells udk the area in which to build the lighting
