Of all the ways to create 3D text in After Effects this has to be one of the bests. Using some very ingenious scripting, Maltaannon figured a way to make the Shapes in After Effects CS3 extrude into 3D space.
It even comes with a handy preset to make things even easier. Maltaannon was working on this ingenious project for several weeks before I released my 3D Text Tutorials so it was really well thought out and comprehensive. Keep an eye on this guy he is a crafty one.
