Look, I sent you a PM telling you, basically step by step what you needed to do, and your response was to ask me to tell you how to do it step by step. As you can tell, i never responded. I am not sure how much better I can explain it than what I did.
There are tutorials, and threads all over this site, and EAMods that i read to learn this stuff. If my explanation wasn't enough, maybe those are. Do some research. They are easy to find.
As far as the BMPs, they came with the uniforms you downloaded. You already know that though, since you told me you tried to update them before.
There is not much else we can do for you than what we have already told you. One thing I can promise you though, is that no one did all of my stuff for me, and no one will do it for you. Asking us questions is not an issue either, but once they are answered once, what more can we do?
We can ask him silly and foolish questions over and over like he does to us.
