Well one thing I just noticed when I tried to fix your problem was that DAZ doesn't use Poser's hair prop files if you made a morph for a hair prop you would have to save it in the Poser Props directory instead... [also don't forget to go to Object >> Spawn Morph Targets and then delete the Mag 1]. You could also try this... after you have finished the morph do the following:

1. Export the entire hair object as wavefront obj (check the "Include existing groups in polygon groups"). [This is so that it will keep the materials and groups.

[Here you have 2 options, the first will be in step 2A and the second in step 2B.]

2A. [Only if hair is a hair prop] Select the hair prop and go to the properties tab. Click on "Load Morph Target" and browse for the morphs obj you just exported. Now name it and click okay, if all went well it should be there. Now just save the hair in the Props folder [not the Hair folder if you are going to use it in DAZ]. It should work now as long as you remember to put the original geometry in the right place and all that.

2B. [Only if hair is a figure] Download Pozers Little Helper from http://home.online.no/~kjellil/Index-AllStuff.htm... once that is there you can use the tutorial to set up a project file. Now another good program to download is Morph Manager, from http://www.morphography.uk.vu/utilities.html {scroll down to MorphManager}. Use morph manager to add new channels, and then the hard part is using CR2Editor {also from morphography} to change the names from IC_01 to PBMCC_01. You have to do this if you're using PLH.

Anyways once that part is done all you have to do is load the original hair geometry (ex: egghair1.obj) and then load the morph (ex: egghair_wind1.obj) and then click on the generate morph tab and change the settings then just hit Generate! After that the "Setup Injection Files" will appear, now the settings that you made while making the project files will appear and you can save the deltas, visibility files and the pose file. [note: the deltas and visibility files work better while in the same folder.]

Okay now it should work unless you changed the vertices or renamed the groups... or forgot to change the channel names like I said before.

I know this is a lot, which is why I suggest you try just saving the hair as a prop and all that first... maybe someone else has a better solution, who knows...

Hope this helps! :D
