I used this system in my animation and can garantee its performance. If you want to be sure about it, go to my YouTube channel: UncleVlad Works.
Features:-Kerbin with its moons - Mun and Minmus-High resolution textures (16k)-Tweaking rotating system: Kerbin around itself and moons around Kerbin-Good looking glow effect for Kerbin, which, also, can be tweaked
The main program is Cinema4D. Hope it will help you! Enjoy!
