i don't see eFrontier as obligated to come up with a solution that works for d|s.  they did modify poser- pmd morphs can inject morphs into a figure without pre-existing channels.  there are, iirc, several threads about how to do this with v3.  though i've personally had some issues with them.  posermatic already released his update to nbs that does this with python.  so i know of 2 ways already in practice.  that d|s can't is definitely not a poser issue.

pjz99 - whoa.  not only do i  never do that, there are several i've re-rendered with new lighting or new materials.  i do varying amounts of postwork, and i have several (read 10+ easy) images that have only gone through the rendering phase.  meaning i might need to re-render them if i get new treatment ideas.  and some scenes i've given up on, planning to get back to them when i have better skills or inspiration.  and then there are the images i wish i had the original of.

i can understand why you work differently, though.  your stuff is kind of narrative, and the characters develop.   a render is just one scene, and not even one that's part of a larger work yet, so i can see getting rid of them once they're completed.

anyway, i just have to say  you guys have made installing v 4.1 sound so complex, i haven't bothered to download her yet.  and i've felt her morphs were sorely lacking.  personally, the empty channels are a big deal, because i like 3rd party morphs a great deal.  v4 isn't as useful to me as v3 and a3 until capsces adds her morphs and posermatic addresses some of the missing gravity issues and a more natural shape to her breasts.  oh, and she gets some ethnic morphs.  i mean, she's a nice figure and all, but i only ever use capsces versions of figures and pretty much always use her morphs.  and i miss them _ a lot_ when i use a figure that doesn't have them.  the eye and nose shaping alone just can't be beat.   but i certainly wouldn't want to restrict myself to only capsces morph sets.
