I opened a skin in photoshop and it seems that where ever it is transparent that's where the player's team color is shown. So I wanted to add face paint to the archers like the rangers in WC2 but it makes it see through. So I need to now how to make this work!
the alphas are actually in the model file (eg Man.mdx) so unless you model edit it and make / or take alphas itll always make the alpha you created transparent (unless it has already been alpha'd by blizz)
