Did a similar remap back in P3 days. If AprilYSH's P4-Vicky remap does not work for you and you really want a giant hirez face for Posette, make the face a new material and enlarge it to fill the template. This will of course overlap the other materials, but it does not matter because you will apply a separate map to this material (like vicky). btw, 'exporting' the obj from Poser wont work. Rather, use the existing .obj in the geometry folder. (backup, etc. as cautioned above). Also wanted to ask you about an unrelated tech problem it looks like you've delt with. Sending a IM.
