Hello !!
I'm sorry, i tried to post it in Bugreport, so i'm pretty sure the
moderators refused it since it was more likely a newbie question...
I have a room, closed, and a light inside.
The camera is outside and looks at the room...
But at the bottom of the wall (from the outside) i can see a kind of light
(maybe 1 pixel only) and it is there only when the light inside is ON.
So here is the quesion : If the light is INSIDE and the room is well close,
why do I see this from the outside ???
Sorry, the comments are in french... and i'm feeling too lazy to translate
them, i just hope you won't need them.
Here is the source code and a link to the picture...
