I have a background bitmap on a 2d plane that has the sun coming from behind it (the way it is), and I want that sunlight to come into the building but the background bitmap/plane is blocking the sun...how can I have the bitmap still appear but let the sunlight go right "through" it? (I have a separate infinity light to illuminate the bitmap).

check hidden for GI global illumination for "background" plane

if I understood right what You are going to achieve
