in additive mode. it doesnt work what so ever (to show the approximation).
when i have the light just near the dge, it does how some ligh pattern, but when tis completely within the hollow cube, its pitch black :(
the level is perfectly lite when i use the build button.
but its annoying not to see an aproximation of your lighting, when just casually editing.

for some odd reason, it works normally on subtractive mode. saltouh sometimes it does show weird patches of darkness, in mid air!
any ideas whats happend?

I would say don't put your light inside the floor and it shouldn't be a problem.

as i said in my 1st post....

when the light is placed properly inside the cube. i get no light what so ever.
the cube is completely pitch black.

the only way to get the light to work at all, is to place it midway in the edge.

:(

Try turning shadows off on that light.
