You really need to teach yourself and there are ways to do that.
You can find a lot of helpful and useful information by searching through these forums which will help you and help you get models into FPSC. Studying the media which comes with FPSC itself and with a little trial and error you can discover all you will need to know about making them FPSC ready yourself.
You can find information regarding modelling and animating at thousands of web sites on the web.
Some of the best places to start are at the modelling program web sites if you dont know where else to go - many like the Milkshape site will have tutorials and other tips and by downloading demo or evaluation vesrions of the programs you can make a practical start if you dont own full copies of the software.
Good luck and welcome to the FPSC forums.
