The way Poser works, the Deltas for a morph take up a lot of space in the .CR2, and I often see them with 7 or 8 decimal places. That works out as tiny fractions of a millimetre, and seems excessive. It's often much more precision that the .obj file stores. Is there a Python script (or Perl or Awk or similar, but Poser has Python included) which can truncate this data? When a Parameter velue of 1.0 shifts a vertex by the Delta value, can anyone see the effect of that 7th decimal place? And sometimes you get a burst of scientific notation; 7 or 8 significant digits with an exponent. 1 part in 10E12?

Forgot to say: this mods the 'v' lines as well as the 'd' lines. Most CR2s don't have 'v' lines, but a lot of mine have internal geometries....

Thanks. I did a little test with the other problem I see. Some values are of the form: 1.2345e-005 Poser 5, at least, has no problem with the form: 1.2345e-5 Only 2 bytes per value, but it was over a megabyte from the CR2 I tried it on.

Now tested... Set to the default, it trimmed 7MB off a 31MB .cr2 That may be excessive. Some of the morphs did seem to lose a little definition. One or two, such as NavelGone, do need more precision. Nevertheless, it pretty well works as advertised. Thanks again.

If that's too much, try changing the 4 to 5 as mentioned in the comments at top....

That's the advantage of experience.... having lots of templates floating around, which can be quickly modified to serve a new purpose. The disadvantage of experience is the tendency to say "Oh, I know that won't work." A beginner starts with the assumption that everything is possible, so goes ahead and tries it.

Yes, 5 decimal places seems to work. Possibly not so good for close-ups, but since Aiko and Hiro (the recent/new DAZ anime figures) don't use morph INJ/REM methods, saving over 10% on each figure is a useful improvement.

Wow - this is fantastic! Thanks ockham. I assume it's valid to do this for pz2 and pz3 files too?

Hmm... Yes, I guess you could. The 'v' and 'd' lines are the same. The file-open dialog looks for CR2, but you could either change that or just type in a different name. Nothing after the file-open is CR2-specific.

I just flicked through a .obj file, and it looks as though it would work on that too. The same "v " lines. You could probably cut back a "vt " line too -- is that the UVmap data? -- but it only has two values.

Cool stuff. I love threads like this. Kudos to Antonia and ockham. Anton Kisiel

this is great! it's just what I needed! I was able to get a 6.3 mb file down to a 4.7 mb file with no morph quality loss... I am one happy camper here! thank you very much! :-)
