It's unlikely that I'll be able to do RGB sabers without the SDK.
And this applies to any of the cpcs (customizable player classes). It's the skin color for the twi-lek and the clothing color for everyone else. This will work for any new cpcs as long as they configed it for color selection.
Anyway, it's out. You can get it here (
