@Joe:

I'm not sure what your workflow is but I know there is a mirror feature built into the morph brush. I seldom ever use Poser's morph brush (zbrush has spoiled me I guess), but on the occasions that I have I can't really recall having a problem with its mirroring features. I do use it to split my zb morphs and that has always seemed to work well for me too.

I thought there was a built-in way to mirror magnets, but that's another feature I rarely have a use for so I haven't looked into it that far.

I generally have never needed to use many python scripts in all my years of Poser'ing so I can't really comment much on it being such a deal-breaker. I can understand the frustration tho for folks who have favorite scripts that no longer work in P12 and haven't been updated or replaced due to the original creators moving on, or in some cases passing on. (I do have a dire need for one script currently that I can't seem to find an equivalent of and for some reason have never been able to adequately explain it to anyone that understand python. I'm highly tempted to figure out how to write it myself as it should be fairly straight forward and simple to accomplish. Maybe I should dig into learning Poser's python).

Maybe its different for folks using a mac, but I have P11 and P12 installed on the same drive on my PC and both seem pretty stable. I haven't run into any issues with one corrupting or causing problems with the other, and the same runtimes are loaded into both. I rarely need to open P11 anymore but sometimes I do just to check certain things. I do have one script that requires P11 but I use it so rarely it's not even an issue for me to boot up P11 for the few minutes it takes to use the script, save the work and load it back into P12. And I mean rarely, like maybe once every few months if that.

P12 has a 21 day trial you can download from posersoftware.com. That could help solve some of these debates and give you a better understanding of the improvements its made over P11. At least then you could argue your disagreements from a foundation of having tested them out first-hand. And I don't mean that as an attack on anything you've said, I can agree with much of it, at least in terms of what Poser's figures need, and I've always admired your work as a character artist and the things you've done with the older figures. It would have been ideal if Poser had created its own set of in-house figures years ago and stuck with them to evolve along side Poser's evolution and not depended so heavily on a 3rd party source. But that didn't happen, so here we are.
