Hi cobaltdream!

I have a method to create morphs in blender on more than one body part, and then exporting those back to use in poser without using a 3rd party tool.... Only skimmed over the rest of this thread so if im missing the point, just ignore this post....but if this is what you are looking to do and don't have a solution yet, I'm am more than willing to share how I do it...Just let me know if you are interested because it will be a good bit of typing!

I use Blender 2.44!

Cheers
