UPDATE: i'm gonna try lighting the rooms with glass walls from the inside and putting the outside light sources at places where they dont directly hit the concrete side of the glass walls this afternoon.
what i did yesterday was: took out all light sources except one and put that close to one wall. the concrete wall it was shining on, that glass looked like nodraw. however on the other side of the "room" i had the same except wothout the light. here the concrete outside was not hit by light, and the glass looked fine.
(light)--> C l G-----> G l C <-- (no light)
C is concreteside,
G is glassside,
l is wall
right side glass was ok, left side wasnt
