STEP 4 Using the background layer as a guide, rebuild the deleted polygons just as they were, using the points on your new head AND the old neck. When this is done, select all the polygons in your prop head (including the new ones you just created), and assign them to group "head" and material "SkinHead". Now, delete the background polys, and export your new geometry as an OBJ file. Put it somewhere in Poser's Runtime:Geometries folder.
