First and foremost, I hope to not start a war over this or to lose any respect I've managed to gain here, but please read the following in the mindset of "suggestive criticism" rather than "critical reprimand":
I'm sorry Kainzorus, but please bear in mind that forgetcanon has only made two posts, with the first one being to thank me for a link to modding tools since SWK was down at the time.
That being said, unless they're a long-time lurker or are active on LucasForums, they probably don't know too much about modding the game.
Given the most-likely lack of experience, it's no wonder forgetcanon would look to the foundation of the character to make changes to the character. I don't know if they know about the .utc files, so they will most likely appreciate someone explaining the files and how to find them.
Again, I don't mean to start a war, and I don't want to offend you, so if I do then I apologize.
@forgetcanon:
While I do not know why you'd have issues between the male and female versions of the models, I do know that what Kainzorus Prime said would be the easiest way to enable your changes.
The .utc file is what I consider the Universal Template for Creatures and is where a character's data is stored for the game to use. When you open .utc in KotOR Tool, you can edit their Inventory with a button at the bottom. This also allows you to change their equipment.
So, what you can do for Revan is to make a disguise item like the Sith Armor from K1 and equip it to Revan's chest slot in KotOR Tool.
To find Revan's .utc file, it depends on whether you have TSLRCM installed.
If yes, go to KotOR2->ERFs->Modules->711KOR.mod->R->revan_fake.utc
If no, go to KotOR2->RIMs->Modules->711KOR.mod->Blueprints, Creatures->revan_fake.utc
And if you need help making the disguise item, people are willing to help if you ask.
