There are plenty of threads that can help you out. Work out what you need to do exactly (WRITE it down) and then you can ask pointed questions - as right now its just too damned general to get help). Also - once you know what you wish to do, then try to search for how to do things - there is a thread up top that claims to be for everything. That will help you out ALOT. Ask quesitons when your stuck, but don't ask first - ask after searching/trying, as to type out "how to" for people takes alot of time and effort for NOTHING on our part (they don't get paid at all to help you!! They get nothing at all!), so don't expect everyone to bend over backwards if your not willing to actually put in the effort to try to find things out for yourself. It may take an hour of searching to find out how to do things, but tutorials to tell how to do stuff also takes about an hour to write, so who's time SHOULD be used? Please search like a nutter, cause at least if you get stuck in a tutorial we can give pointed guidelines/help with you easier!!

Good luck, and the ships have already been made for you - see TFK-Killermatrixs mod. You will have to email him for permission to use his models though.

If I am not mistaking there is a mod of BABYLON 5 out.
It is out for a year or so.
