We pay great attention to 3d-sprites. This is a number of object’s pics from different views. We will talk later about choosing the right phase, but now lets have a look at lighting issues.

The problem is that sprites don’t have any “volume” and geometry, and they have to take part in scene lighting process. Anyway, we can enlighten all the sprite, and it still gives nice effect.

If the light is between camera and sprite, is lights the whole sprite, otherwise it doesn’t. And - we have to be sure about color, power and attenuation.
