Creating Mods

[Brennos75]

Hello, I've been playing KOTOR and using mods here created for the game for a few. I'm interested in creating some new mods for both the K1 and K2 games, and I've never created a mod before. I've been looking at the various modding tools available, and I can't make sense of where to begin. I want to make a mod that changes all of the masks in the game  into full helmets, and write the mod to make it compatible with the BOS_RS mod. So I'm asking for some advice on the forum from the more experienced modders here about where to start. Any help is appreciated.
