Apologies in advance if I'm confused about something: When *loading* the rad
data, did you use the accepted 'witchcraft' thing of setting both
pretrace_start and pretrace_end to 1 (along with always_sample off)? Or did you
run the loaded data with the exact same rad settings that you saved it with? I'm
curious if either one or the other made any visual difference (that is, any
difference from single-pass radiosity.)

BTW, *funny* cat image!
