Sith Pureblood Customization

[hk_a1994]

Alright soooo I've been trying to either come up with my own customization for Jaden at the start of the game to make him into a pureblooded Sith (for those of you who don't know or haven't played swtor, they're basically evil looking red skinned species that inspired the sith order). I found a mod that was already completed here: https://jkhub.org/files/file/3358-sith-pureblood/ and I tried to just modify it to make it a customization option but I couldn't get it to work. I tried making an npc file for it and I even compared the player model folder to another file that was a customization option and creating what looked what was needed to no avail. I'll admit I'm relatively new to the whole modding thing, so if there's a simple solution that I've just overlooked then I apologize lol. If that one can't be done tho, I'd love some help with making a completely new one and just have it look like this, with the basic Jaden clothes I guess
