I see... But I don't think the 10x10 improved the quatlity that much. Have
you tried 3x3? 4x4? Maybe it would me just as nice and one third the
rendering time? Maybe it looks crappy, but have you tried? I never use that
much myself...

I have only found a vast improvemt over the 4x4 area light when i use 3 4x4
lights each aligned along on of the 3 axis - sort of like the peice of graph
paper used by someone here - forget who!

however, i have rended some images with upto 30x30 lights, and was very
impressed with the results, especially for simulating sunlight..

my chem education was totally different, we had a limit on certain colors,
so 'pretending' was required... maybe thats why i never took chem A levels
at high school - that an the chem teacher was a nutter - dropping a 1 inch
cube of sodium into a water filled wine demijon thingy definatly gave me
that idea, or was it the time we decided to make WW 1 mustard gas, only to
realise that the vents were knackered and the class next door got all of our
interesting concoction......  happy times   [sigh]
