Question - I only recently have begun using more complex characters with V3 and Poser Pro Pack that include the full head/body morphs. Correct me if I am wrong - but it seems that these morphs create a large file size (and proportionally lengthy renders). To make a long story short - if one is to only use some of the head/body morphs with a particular character - can some of the others be deleted to reduce rendering time/file size/etc...? For your consideration - I thank you.

That's a part of the reason for the INJ and REM pose system with V3, which can do at least some of this. It also means that you can easily sort out any mistakes if you delete morphs by other methods. I'm not sure that it actually changes rendering time to remove a zeroed morph, but it will cut file size, and that can make a difference with several figures. Anyway, it's worth trying.
