How i can do unit setup in wings so i can set the metric unit to meters?

Yes, but that doesn't help.

I am experiencing a problem where I created a room in Wings3D using 1WU = 1M. The room is therefore about 10UU x 20UU x 10UU high. when I put maxxed out baked lights at the ceiling, the light never reaches the floors.

I'm not sure if this is the actual problem, as there is no information about what Unity expects the size of a room to be for lighting purposes.
