Viewing 3d shoes

I know that steve and other oatchers give these "renders" of their shoes, ut I was wondering what files and what editors you need to make your own views. This is helpful so if I am editing any shoes, I can see results quicker, and make the appropriate fixes

use oedit. and open up any mesh of a cyberface. theres a part there for the shoe. i think its the last one... then you can load the shoes texure of your choice... i dont know any other methods though

I've tried that, it's not really helpfull because the map doesn't match our shoe image.
So after applying our shoe image texture, it won't appear correctly.
Off course we can just edit the map to match our shoe image,
but I've tried that too and it's really hard.
anyone can help ???
