As stated above, you'll need to use a 3D model editing program. There are many to choose from: Maya, 3DS Max, Houdini. But only 3DS Max is has a plugin that allows you to export models for use with the game. http://www.discreet.com/3dsmax/ Discreet wrote 3DS Max. Sadly, I don't think it has a free educational license. Maya and Houdini, however, do. I recommend Houdini, as it is a little easier to use and doesn't plaster logos all over your renders. http://www.vislab.usyd.edu.au/sidefx/ That's a mirror for the Houdini Apprentice license. About making races, you'll need to create model for each body part. A model is a file describing what the piece is shaped like. I'm sure you've seen pictures wire-frame objects. That is a model, but without textures. Textures are files that get wrapped around model at runtime(when the game uses the body part). Obviously, you'll need to make both a model and a texture for every body part you wish to add. There is probably also a few other things you may need to do to make your new body part work with the TES, but I just found out I had a TES. ^_^
