Hello. I've just finished the 2D and 3D tutorials, and want to try to make something on my own. I've decided on doing an air hockey styled game, with Vector style graphics. I'm not actually drawing lines however, I've made sprites in Paint (paddles, ball, etc.) with white outlines and black fills, so they look like vector graphics. Is there a way to make the black part of the sprite transparent so that if say I want the background to be whatever color (other than black), the black corners and insides of my sprites won't show up? Thanks!
