Sitting or any other poses that cause more extreme bending of the appendage tend to cause some joint "breakage" in Poser. It is a limitation of Poser. Particularly the hip, knee, and elbow joints tend to break when bent too far. For best results I model my poses using the standard P4 woman (to ensure they will work with any P4-based figure). I then apply the more extreme poses to the Eve3 character which has superior bending capability. This will still yield some joint breaking so I eliminate the artifacts in post-render touch up. Krel
