The most I've ever loaded into DB is a textured static model from blender. It may be possible to get animation but I never had good results importing most anything into DB. Blender's export may have improved since I last tried but I'm not sure.
About the edges, its kinda odd because they are set to smooth I think the edges on the head have somethign to with the texture cuz I had to do something sorta weird to get the face to show properly.
Explain to me why some people pay money for 3d software? Its not 3d till its been blended. wwww.blender3d.org
