Create and animate 3D cogs in After Effects - Part 2

Thanks to the new 3D capabilities of After Effects CS6, you can create and animate 3D cogs and gears inside of After Effects without the need for a true 3D program.

Part 1 demonstrates the problems with trying to animate cogs, and how to solve them using standard 2D techniques.
Part 2 shows how to build on this technique with the latest features of After Effects CS6 - producing extruded, ray-traced cogs and gears that animate together perfectly.

The important thing to realise is that these tutorials show you how to create your own cogs from scratch.  This opens up endless design possibilities for every type of project you might be working on. Although the tutorial only shows simple white cogs, with a few textures and conventional compositing techniques you can create shiny metal gears, grungy old clockwork mechanisms, medieval wooden contraptions, or even ancient stone artefacts.

The creative possibilities are up to you - I'll leave the advanced designs in your hands - but by using the simple technique demonstrated here you'll know that your cogs will always animate together seamlessly.
