Is it at all possible to do an appearance change in the first KOTOR like in KOTOR2? The only scripting commands I've seen for the process are for KOTOR2, but I'm almost positive I saw a mod with a similar effect about a year ago.

I couldn't find a script function like that for KotOR I, but a good workaround is to make an item with a disguise property and have a script that equips it.

i'm not sure what you mean, if you need a temporary appearance change you can use EffectDisguise(int nDisguiseAppearance) i used that to remake the pc stunts on Coruscant and Korriban, makes them look exactly like the pc, it works for Kotor too. if you mean permanent i don't know.

The problem is that I need a pretty permanent change. At a certain point in the game, I want to be able to change Bastila's look a little bit and have it stick that way. ...and I think I just figured out how to work things to get the result I want. Thanks for trying to help, guys.

EDIT: Aaaaand... it worked. Decided to play with textures and heads.2da, and now she's got a good, sick, pink-eyed look for when she turns to the dark side.
