Instead of using a set of static images for your skyboxes, this asset pack allows you to build animated skyboxes displaying game animations, physics, and game logic in real time.
All you need to do is drop two prefabs into your scene, follow the simple instructions in the readme, and build a miniature scale model of whatever things you want players to see "off in the distance."
Comes packaged with two sample scenes using standard assets and placeholder art for demonstration purposes: One scene where you stand in a small, fenced in platform, and watch in first person as a giant boulder rolls through the landscape and topples distant skyscrapers. The other lets you play in third person as the default Unity construction worker, but puts you in a skybox area surrounded by tiny, breakable buildings. Watch as the destruction in the foreground is translated into large-scale devastation in the surrounding city!
