I have created some rotating text in AE using CC Sphere. In rotating that text, is it possible to have it disappear behind another solid and reveal again in front of the solid and not see the reversed image as it rotates. I have had no luck trying this with 3d layers. If anyone can offer any suggestions they would be greatly appreciated!
Do you have After Effects CS3 or later? It's possible to do this with per-character text animators and avoid CC Sphere entirely. Then the letters will behave as independent 3D layers that can be occluded by any other 3D layers.
There is actually an animation preset for this. Try typing in "3d rotate around" in the effects and presets panel.
I'd encourage you to explore the settings for this preset and ask any questions you have about how it's set up. This is a great technique. You can even create extruded text that sits along a "3D" path.
