Hello all!

I am trying to pull off an effect where I have a sphereized map of the world (using CC Sphere) unwrap to go back to a flat map of the world, but I can't seem to find any way to do it within my budget (3rd party tools like Boris FX are a little pricey), is there ANY way at all to pull it off just within AE, and if not I will take the next best solution.

Thanks in advance!

Use the Optics Compensation effect instead of CC Sphere.

Alright! Let me give that a shot!

After playing with it and looking around for a while, this isn't quite the effect I'm looking for, I might be missing something though, is there a tutorial or something you can point me to?

Hi Luke,

I don't know if there are any tutorials for the optics compensation method. It just came to mind trying to think of any built-in effects that could be used.

The next relatively good option for creating a spherical warp with built-in tools is mesh warp (plus a circular track matte to make it appear perfect).

A more complex option is to use an animated displacement map (at 16 bits), but it would take me hours to figure out exactly how that would be set up.

I also tried the method of enlarging the CC sphere radius while decreasing the map size -- it ends up looking essentially the same as optics compensation, but is more difficult to do. And it doesn't go all the way to a flat map.

In any case, I believe the key is to come up with of a good way to animate a plane wrapping into a sphere rather than the other way around. There are several ways to do this, not sure what is the best for you.

I think that is actually a really good idea, I'll poke around to see if I can come up with any solutions!
