What color is used for Alpha Channel?

[Bixel]

I forgot. But there is a color used by the shader that tells it that its an alpha channel. Is it Cyan?? Used for detail that require no geometry like a railing or grill.....

Alpha in the game is done with a separate map. White is visible, black is not. There are no half transparencies.

Be careful, the alphas can cause problems when you zoom in or out, see this tutorial :
