Hello,

For a school project, I am trying to simulate a solar system in Motion. In order to make it look really nice, I would like to make it from a perspective that shows 3 dimensions, like this:

I thought I would go about it by setting the planets, orbiting the sun in the center, on a pre-set circular motion path, and then manually changing the z-axis...but I can't touch the z-axis!!


What would look really cool is when one smaller planet orbits the sun, as it goes "behind" the sun from the camera's perspective, it will disappear: that is to say, it will not only get smaller, and negative on its z-axis, but also once it reaches the edge of the sun, will go "behind" it to make a 3-d ring effect around the sun.

Any suggestions??

Thanks everyone
