Lightmap Problems

[Frits]

I think found the problem, when I removed the top and bottom faces there are vertices on the upper and bottom edges that are not connected anymore to each other. I made a new cube and now the baking goes right

But, there is always a but, I see another problem, the walls on each side of the lamp are lit ok, but the walls behind the lamps are not completely lit (see white circles) only a small circle.



Anyone an idea?
