Download DAZ-Studio.

Under content, you'll find a folder called LOD.
It contains four LowRez objects of V4:
V4_LOD_1K.obj
V4_LOD_2K.obj
V4_LOD_4K.obj
V4_LOD_17K.obj

Import them into Poser and use the SetUp room to ad V4.2's bones to each.
Then delete V4.2's morphs with MorphManager.

If you want working morphs (in Poser), use Cage/Spanki's morph transfer script to transfer V4.2's morphs.

Or wait until DAZ releases his cr2 export plugin (soon!) and export the LODs with all their morphs directly out of D|S.
