TPF - Package Build Help

[EightLights]

Since there is no Mass Effect 1 topic I figured I went over to the closest thing that might actually get me help :rolleyes:

 

I'm trying to re-texture the human male heavy onyx x armor to something that resembles me2 and me3 armor, and so far so good. I extracted the texture from an existing tpf mod here on nexus, altered what I wanted and now I'm having trouble getting it in the game.

 

I have tried extracting the texture from the game, alter it, save with the same name and then building the package but it's not working either

 

Any suggestions are appreciated, thanks~
