Ok, forgive me for the noob question, but, I'm at work (the manual is at home) and now this is driving me up the wall!

What exactly does the "Max Bucket Size" mean and do?  I've never touched it for anything, simple because I didn't know what it would affect, but, I've never had any problem with renders in the past...I'm going to be so torched if altering the numbers make my renders look better! :scared:
