Thanks everyone. I've taken out all the objects that werent within the production frame. That should help. I'm still trying to solve that leaking light problem in the back corner though. I made sure cast shadows was checked, changed the floor from a plane to a solid form and raised it a smidge to make sure no space is left between floor and walls.....but I still have light leaking in. As a test I removed the light behind that wall, and the leakage did in fact vanish. So it is caused by that one spolight. I'll keep working on it and run some more tests, try the GI again, perhaps on different settings. I'll let you know how it works out. Thanks, H&B
