I didn't make it!
Okay I'm a noob... is it possible to have a robe from KOTOR 2 to be used in the first KOTOR? And if it is, can some one help me? Thanks in advance
It is...but it isn't exactly legal. It's called porting, and the mere mention of it stirs up ugly emotions on most occasions. So no, it isn't possible.
If you want to do it the other way around, bring items from K1 to K2, is possible, since there are some models, textures and item files unused and left over. But doing things the other way around isn't possible unless you start from scratch.
The closest to what you want is modeling. And some major. You'd have to have the Star Forge/Revan's robe's cape, and well, it'd be a project in itself.
