Hey anyone have any quick tips for getting this guy to sit naturally in the chair?
Keep at it. Bend the knees as far as you can, using the calves to support Palps in the chair, pulling him forward off his backrest a bit. Bend the chest as much as the torso and tilt the head forward. Futz until he looks right. Draping the robes properly helps immeasurably in selling a comfortably seated Emperor so he doesn't look slouched.
