Modding C&C 3 Thread

I'm writing this thread because I wanted to do a mod for C&C 3 Tiberium War, but I don't know how. I used to mod Tiberium Sun ages ago, but I forgot how. Any help would be appreciated. Also I'd like to know how to create my own graphics and units models because I want to make a new faction, not just a balance mod

groups and tutorials in groups

also checkout cnc3.net , Commandconquer3.com , thundermods.net , cncguild.net, also many mods have free source code to look at and read through... including my failed mod.
best of luck and may you actually release one in due time

I'm new to modding games and want to make a mod for C&C3 T W which engine do you recommend?
