    Hey all,

    I am currently working on a project where, in essence, I need a 3D, rotatable earth (which I have been creating via CC Sphere) I need to have a pillar of light shoot out from OFF the surface of the earth over New York City.

    I’ve tried using Trapcode Shine. What I’ve done is take a white sold (10 x 10 px), created a null object and parented it to the white solid. After that, I’ve created an adjustment layer and applied shine to it. For the source point, I’ve set an expression as “src=this_comp.layer(“Null 1″); src.to_comp(src.anchor_point)” This effectively allows me to have the shine come OFF of the object in 3D space.

    The problem I am having is that I don’t know how to attach it to the earth. It is a comp that has many different layers tied to it via expressions, and pre-comping not only screws up the expressions, but it also doesn’t render the light pillar properly.

    Does anyone know how to create this effect? I am up against a tight deadline, and any input is greatly appreciated!

    Thanks!

    This is just a shot in the dark but have you thought about parenting the whole shibang to a Controller null and animating that. You could place that null in the center of your sphere and place the light coming from New York. Set an expression so that the rotation of the Controller is the same as the rotation of the sphere so that they move together.

    I couldn’t say for sure. I would have to look at it to be sure but that sounds like it might work.

    Why not just create an additional version of the sphere that has a wholly black texture map with a white point at NYC, set the blend mode to ‘add’ and apply the shine to that? Then just make sure that the animation of both spheres are linked via expressions.

    Would that work for what you’re doing?

    What steps did you go through to create a revolving earth with CC Sphere?
