I want to revolve a sphere Form layer around another in 3d space. Normally I would do this with a null object in the center (or even move the anchor point in the center) and simply rotate the null. I can't seem to figure out any way to do this with 2 trapcode form layers.

I made a tutorial using VC Orb layers to create Mars and its moons. I don’t have Form, so I’m not sure if it’s applicable, but I wouldn’t be surprised there is the same challenge in that parented nulls don’t have global coordinates.
