I'm practicing with a mesh body from a game. I'm using XPS to import it into Blender, but the body mesh appears to be separated and not one uniform object. I can't find the mesh listed as an object in the layer tab either- am I uploading it incorrectly?
Sometimes Importers will separate things into multiple meshes, or even multiple separate objects. It looks like the mesh in the picture is still one object, but the mesh has been "cut" along various seams. First thing to try, in Edit mode, select the entire mesh, open the space-bar search, and and find the "Remove Doubles" tool. You may have to adjust the merge distance option, depending on the size of your mesh.
