Last night I started a render, in which the first few minutes looked fine (as in the render looked correct)
Woke up this morning, and it was SEVERELY burned. pure white, except for a few spots that were in shadow.
Nick, are you sure that there isn't a looping bug causing the "burn" effect to happen more than once on the same data? I ask because it seems to get worse over time.
Same scene (which I can email you, if you'd like) in .6 t2 looks fine, as is .5.
.6 t2:
