As has been mentioned, I built and sell a set of original figures for the Sims, you can take a gander at it per the link. Mine aren't converted Maxis mesh, incidently, it is all original. What did I use? Max to do the modeling, I wouldn't want to actually model in Milkshape, but you will need that for file conversion and assigning parts if you model in another program. You also will need SimBlender, plus (probably) Sim Pose for doing pics, you can find them at the various Sim's sites. Plus you will need some good programs to paint the textures, Seamer did an excellent job onthat part on the set we sell. With the Sims, good textures are excedingly important.
