Hey
Hopper: Thanks ! I have, you just don't notice it that harr because of the brightness of the outside light.
fusion2007:
Here you go. Scene was lit with one area light for the sun combined with a self illuminating gradient texture(greyish to blueish) applied to a cilinder around the loft (Rendertime was 52 min on an octocore 2.8 btw.)
COBRASoft: Thanks, nice to meet you !
