Can someone please explain to me the alpha channel
In my particle system engine that i''m creating, I use TGA files for the particle textures. I would like to know how to use the alpha channel in my textures. For instance, if I am using a basic solid circle for one of my particles, how do i set photoshop up so that when I load the TGA in my particle system only the circle will show and not the background stuff? Thank you.
