Lars,
I don't have enough experience to comment on the usefulness of your proposed method, I can only say that I used the method on single large images (I'm up to 36,000x36,000 now). My main goal was to prevent any caching of ambient points due to memory limits.

Hi,
Mark did some work on how to get nice results without ambient cache (afaik he uses -aa .00 -d 6 -ps 1 and downsamples /4 in pfilt). I tried the same on a very large model, but rendering is slow now because the different views can't share ambient data. So my suggestion is to keep low -ad and downsample as proposed, but cache the fewer ambient values in an ambient file using a moderate -aa. Any comments? I wondered why this was not mentioned in the studies, am I completely wrong or is it because he simply did not have to reuse the ambient values (in a comparision with different ambient settings, that would be a bad idea ;-)?
TIA+CU Lars.
