17 Choose edges along which you wish cut shape to body part and use "loop cut"
18 When you cut shape for body part check if all unvisible polygons (where body parts touch each other) have "hole" material. I always miss some polygon and must do it again.
19 "rename" each shape with body part name: hip, abdomen, rShld etc.
20 Select created shapes and "export selected"
21 Import obj to Poser, go to setuproom and load bones from library. As a donnor use figure (blank) for which you created clothes.
Above are smaples which I created for M4, M3 i V3. Conforming or hybrid.
