UV Wrapping

How does one go about changing the UV wrapping of a model?

download Vertex Modifier, open your model in .mdl format and then go tools, UV Mapping, then load the background image as a .jpeg.

Sounds like French to me =\...

I've gotten to opening up the UV wrapping area, but I don't know precisely what to do from there...

its easy, you just drag the points around on the uv map. that determines which parts of the skin the faces of the model uses.

left click and drag selects points, right click and drag moves/scales/rotates depending on which button you've got selected at the time.
