I think there are some modelling tutorials on
Machinima. Once your player model (if that's what you mean) is done and skinned, you'll first have to look at the default TournamentPlayer classes to see what animations there are. Animate your model and export it. You'll then get a <name>_d.3d, a <name>_a.3d and a <name>.uc file. Make a subdirectory in your UT folder and give it your package's name. Create a subdirectory called Models and one called Classes. The .3d files and the skins go into the Models directory and the .uc into the Classes folder, or at least that's how most people do it. You HAVE to put the .uc file into Classes, or the compiler won't find it. Once you've done that, edit the .uc. Change the paths according to the actual setup you decided to use. You'll also have to look for the texture imports, they're set to texture1, texture2 and so forth by default. Correct that, and then make your animation list by imitating that of, e.g., TMale1. Then make an entry for your package in the UnrealTournament.ini, as an EditPackage. Run ucc make in the System directory and that's it, I think. If your model looks wrong in UT, try changing the scaling in the .uc and recompiling. You'll have to delete the .u before.
