I find the best way is to export the figure from the zero position from Poser as an obj file. Make sure the hips and body are both zeroed on all axis and use the joint window to zero all joints. You will need to turn off IK. When you export tick the box that name the individual parts and do not weld the seams. The mtl file seems to add a number to each material name but you can edit that later. I find I need to scale it up by 10 when importing into Wings. Hope that helps
