Hey Danny, Not that I'm thick or anything. I follow your tutorial very easily. It would be fun if you did a video for the N00b's.
Great Job
One small correction though to your manual. All you have to do is change the C2 to a C1 in the first byte second character and Umodel will read and extract the file perfectly. You don't have to export it again though UnrealED 2004. I tested it and it works with Animation, Textures, and view only StaticMesh.
Also the same trick works for Textures. Go to the Killing Floor folder, and make a copy Characters_tex.utx now rename it to just Characters.utx, then change the C2 to a C1. Then open it in umodel, and it will work perfectly.
Do the same thing with Static Meshes (*.usx) and you will see it in Umodel. (no export of StaticMesh has been implemented yet)
For those who are absolutely clueless, and don't have a HEX Editor. I want to thank Chrrox for recommending HxD Hex Editor to me, It's really easy fun and it's Free:
