I have a problem Mod

[Pinmasters]

Hello, I'm here to ask you something very difficult to do.

I wanted to know if you can add more than one default texure to the game itself.

Let me give an example: I have the texure "lowr_diff_000_a_whi"

And I want to add another texure who reads him in the game .. so I should do "lowr_diff_000_b_whi".

But the game does not read anything to me, who can help me?

Thanks Guys
