I just finished implementing our solar system as a funny exercise with rotation and all. But in reality the rotation planes are tilted, as seen alongside the x axis. So thats like a brick wall for me at the moment, as well as the other thing (not quite important but i tried to wrap my mind around that one too) where the orbits are not circles but rather ellipses. Any thoughts on how to implement either of those??
Information: rotation is done by adding a node, adding the planet as a child and letting the node rotate.
Thanks in advance,
