That depends on how you set up your textures and materials. Can either be a couple clicks or restoring file alignments within PMXe for each one manually. You may also need to set up toons and stuff. Should be able to do it all within half an hour, unless you have over a hundred materials and decide to name them all properly as well. Fairly sure there are googleable guides out there.
