Well, I've managed to figure out how to make new "parts"... so far I've added two heads and one set of pants to the game.
I have a very cool looking character, but he's missing one thing: the robes! I've re-skinned one of the human male robes, 1b I think, which uses the robes02 series of textures in the hm jedi.
Here's the problem: The lower part of the robes appears as one sided in the game! It looks fine (great!) in modviewer, but when I load up the model in the game, you can only see the lower half of the robes from behind/outside. The odd thing is I can get it to work if I use the original filename for the lower robe... this leads me to think that somehow the game instructs certain surfaces to be two sided, as opposed to others. If this is so, the solution should be as simple as adding my new texture to that list....the problem is I have no clue where that list could be!
I know this is a complex question, but I'd love to figure this out cause its the one thing standing between me and being able to essentialy do whatever I want with the skins. If anybody can help I'd much appreciate it.
