I just noticed that if I have a poly patch within a parent patch that downsamples by two, it's output is simply the downsampled values repeated.
Ie the sequence 1 2 3 4 5 becomes 1 1 3 3 5 5.
Is there a way to specify how the output of poly is upsampled to produce its output in the parent patch say to get something like 1 0 3 0 5 0 (ie zero padding). Or possible interpolating...
I seem to remember talking with somebody about this a while back but I can't seem to find any info in the forum.
