I modeled a new figure, and it has the following groups. hip abdomin chest head l_hip l_thigh l_knee l_shin l_foot l_shoulder l_upperarm l_elbow l_forearm l_hand r_elbow r_knee r_thigh r_hip r_shoulder r_upperarm r_shin r_forearm r_hand r_foot I have created the following bones: hip abdomin chest head l_hip l_thigh l_knee l_shin l_foot l_shoulder l_upperarm l_elbow l_forearm l_hand I have read somewhere that it's possible to mirror bones, and I'd like to do that to make the r* bones match the l* ones. How do I do this? BTW, I haven't used the group tool to associate the polygons with the bones yet. Thanks!
