I have read the posts about lightmass and lightmaps, but i don’t get it quite right…

why is the lightmap at my object good, but at the floor it is complete false.
The lightmap res. from the bottom SM is 256.

It is Build with medium preset

I have solved the problem… the SM was the level ground from Epic, now i use a bsp and that works like a charm!

Is that the rebuild light or only a preview?

If the floor is BSP then you have to lower lightmap resolution, this is how it works in Unreal Engine. Try a value of 16 or 8 for example.
