Yes, I think that was what I was groping for. And more data to shuffle around. I ran yout program over the Aiko3 mesh, and it saved about 380k out of 8400k; maybe not a huge amount but it all helps. The coordinates are given to 8 decimal places, with either a trailing zero or ending 98 or 02. Millionths of an inch, if I have it figured right. I don't think it would make any difference in a close-up, and it might depend on Poser internal data structures, but they used to teach about useless precision at school... Well, my school anyway, but that was a long time ago and in a foreign country, and besides... I did some quick checking, and it doesn't actually make a time difference. One Aiko 3 takes 10 seconds to load objects, two of them take 40 seconds. (Would three take 90 seconds?) Maybe I'm running just inside the limits. Aiko 3 is an awkward figure anyway, since it doesn't use the INJ/REM technology; neither does the Hiro figure. So the .cr2 files get pretty big with all the deltas in them, and they're unimesh figures; it needs just as many deltas as V3/M3. (Checks) A lot of the deltas are in exponent form, which does save a couple of bytes each, but still down to differences of a ten-thousandth of an inch. If these file sizes do matter, there's a lot of scope to trim them back.
