I'm pretty sure that I'm getting this problem because the cube in which I have made my room has flipped normals (so i can work inside the cube) meaning that the light is not affected by the outer walls because in a sense they don't exist.
Here is a picture of my scene (if it helps at all, but it is very simple):
Is their a way I can change it so that the face with the window does affect the light on the outside of the room? Or will I have to start again using seperate shapes for each wall so that their is no need to flip any normals?
What is the best way to achieve an interior space that is affected by exterior lighting?
Thanks, any help would be really appreciated!
