How do I make certain parts of a player model accept player color?

We have some player models we edited, but we want people to be able to change the armor sections of the player models to whatever color they’d like. How do we go about doing that?

add an alpha channel to the base texture, then do $blendTintByBaseAlpha 1 to your vmt

White = accepts more color, Black = accepts less color (original color)

To add to the question since I am sure this caused some confusion, how does one add an alpha channel using VTFEdit? I tried with Gimp and it’s plug-in but doesn’t work and there are no tutorials.

Gimp sucks with alpha avoid using it for alpha if you can. Photoshop is the way to go. However, if you can’t nab a copy, you can use dxtbmp to insert a black and white texture into the alpha channel.
