Once I've found a tutorial (I guess, it was made by a guy at the Unlimited Realities) showing ho to make and use alpha maps. The UR site is no longer the one I knew (at least this is how I observed), so I can't find a good tutorial for this...
Here is what I'd like obtain:
There is a 2D environment (hybrid engine needed)
Let's say, I have a FIRE sprite. I want the fire have various alpha values. I mean, at the top it should be more transparent than the bottom. For this I'll make a greyscale picture (black and white) to tell the engine where the sprite should me more and less transparent.
How can I do this? |
