Sorry for the late answer, the ebots are down (at least for me)

"Adavyss, is it true that one can avoid the need for DAZ type injection morphs by using the Poser 6 .pmd?"

Well... yes and no. The general idea is the same, but it has been IMO badly designed.
First pmd files are not text files, they are binary files. You cannot edit them.
They only work in P6.
They are big files. If you want to make custom morph sets, you end up with a lot of big files.

The only interest I see to pdm files is if you use multiple same characters in a scene. They will all use the same pmd file. It can be interesting.

I tried hard and tested pmd files a lot. I reached the conclusion they were not worth using: too heavy, not versatile enough, too limited.
If you want a recommandation, forget about pmd files, you'll save a lot of time and frustration.
Injection technology is still the best for morph management.
