This tutorial shows you how to fly a camera down a 3D motion path.
Wormholes are cool and a sci-fi staple. You'd think you would need expect a full 3D package with particle generation, but while After Effects can handle 3D particles, the real challenge comes from getting the camera to move through the same motion path. In Cinema4D, this is called Align to Spline. I demonstrate how you can use a few null objects, some simple expressions to create the equivalent. And use CC Particle World to create a dynamic, flexible, adaptable tunnel of particles that renders in minutes. All in After Effects with no plugins.
The texture for the particles comes from a precomp which makes it "super easy barely an inconvenience" to swap in different tunnel textures.
