I've modeled a photorealistic scene of the Earth rotating in 3DS Max and would like to use it as a backdrop of a menu screen in a 2D game. What would be the appropriate way to implement this effect in-game, a sprite sheet? That seems like it would require a whole mess of frames to appear convincing. Does that matter?
What if I then wanted to add the moon orbiting the Earth? A second sprite sheet for the moon's positions, with blank frames where it should be hidden behind the Earth?
Is there a better method?
