Totally black equals 100% transparent model, or 100% pure teamcolor.
Totally white equals 0% transparent model or 0% teamcolor.
You probably understood this, but this
only applies
when you are painting on an alpha channel. So you can paint as much black and white on the skin as you want, as long as it isn´t on the alpha channel.
So if I make part of my skin 100 black then it will be 100% teamcolor AND 100% transparent at the same time? So it will be red but it will also be invisible?
No, it will be either 100% transparent OR 100% teamcolor, not both. Which of the two it becomes depends, as I said before, on the material which can be found in the .mdl.
when I make my model transparent by using "Eraser Tool" it becomes white when I convert it to .BLP and ingame instead of being transparent the parts of the body become white as well.
That´s because you can´t use the eraser tool when alphaing. This DID however work in PS7, but not in CS2. Paint with black on the alpha channel instead.
Its like, the parts that must have teamcolor are black and aplha chanell in the same shape, it is just very strange.
It doesn´t have to be that way, but Blizzard does it like that.
In fact, you can paint whatever you want on the skin, but as long as there is something on the alpha channel it will turn transparent or teamcolor on that spot.
Again, just ask if something is unclear. Alpha channels can be a bitch in the beginning.
