Question about face room in Poser

 

I try to edit the V4 head in face room.  The first message I get when I click on the face tab is "your selected figure is not a known face room figure."  After I click ok, a head show in face room but not V4's head.

Am I missing something?  I am trying to use a photo for the head.  After I import the photo and map all the dots, the head look really strange.

I also try face shop for DAZ3D but use it as a standalone program.  The face/head turns out really well and easy to edit.  If I export the head.obj object, can I use it on V4?
