Um okay, I have a kinda stupid question.... but did you turn OFF External Morph Data?

JUST INCASE YOU DIDN'T, here's how:

STEP 1: Go to Edit>> General Preferences... (or press Ctrl+K)

STEP 2: Click on the "Misc" tab, which will give you things like 'Temp File' location and stuff, (this is not important right now).

STEP 3: In that tab there will be a subsection that says "Save Files." Poser has "Use External Binary Morph Targets" checked on by default... you don't want this, you want it turned off... so UNCHECK IT.

Now you should restart Poser (after saving your project), then when you re-open it, you can start saving Props and Figures and Poser will NOT make a .pmd file, instead it will put the morph data directly in the file. So now they should work in DAZ...

If it doesn't you could try saving the poser project as a .pz3 (Poser file) and then open DAZ and click on File>> Import>> example.pz3.... this will open your poser scene and the hair might retain it's morphing capabilities and you could just save it in the Props folder directly from DAZ. Who knows??

I hope this helps...
