Are you trying to make this model appear like a Centaur or a Horse only?
If it's a Horse, the problem is the Bone_Head that still remaind in Node Manager. Try to clean it with Mdlvis.
If it's a Horse man, well the body doesn't appear properly or you didn't add it, try to attach the bones/vertices to their appopriate geoset, btw, does some body of that model part does appear at some random unit in the map by chance?
