here's one that I've been playing with... was trying to light the thing using only GI, and was pleased with the way the render was turning out, until it got to that extremely dark shadow at the bottom of the far wall. Any suggestions to get rid of that? I've included my render settings. Background is simply a blue color sampled from the supplied sky.jpg... texture on the model is the pale pinkish/orange that you can see with no bump or reflection and slight highlight. No other lights were used.
