i have a simple room (box with three holes + shell modifier) with a door and two windows and a teapot in it.
for each of the windows i placed a free area light (direction = ok). when i render, the only thing i get is BLACK - when i place a "mr Area omni" into the room i get a plainred result (the color of my room model !!!).
i saw a tutorial video where the guy makes the same. he has an additional skylight in the sceene (when i try this i get RED too).
i use mental ray as renderer.
im sure it is something simple but i just don't get it.
thx for your help
