Re: Vanishing Point Animation in Ae CS4

Making an element slide across two planes in 3D is not difficult. The hard part will be matching the perspective of the building in the original.
So, one way to slide an AE 3D layer so that it looks like a texture wrapping when going through the juncture of the two planes could be like this:
1. Create a very wide Comp (custome pixel dimensions).
2. Add your layer inside that Comp.
3. Nest this wide Comp in your main Comp (for example, drag it from the project panel to the main Comp's timeline
3. Duplicate the nested Comp in the main Comp's timeline (when you duplicate a Comp in the timeline, the copy is a clone of the original and keeps in sync. When you duplicate in the project panel, it's a separate instance).
4. Enter the nested Comp, and animate the element in 2D from left to right.
5. In the main Comp, crop both copies of the nested Comp with a rectangular mask, so that they overlap perfectly (the masks make the second comp begin where the other ends).
6. Make both copies 3D.
7. Move the anchor point of the second nested Comp (the one on the right) so that it's aligned with the visible end on the left.
8. Rotate the second Comp 90 degrees in the Y axis.
That's all.
Matching the building's perspective is a different subject :)
