This tutorial shows how to use either Red Giant Trapcode Particular or CC Particle World to create a particle tunnel.
Part of my Makin’ wormholes series, showing how to create really cool, sci-fy tunnels in Adobe Video & Motion After Effects. Christopher Nolan’s 2014 epic Interstellar attempted to scientifically accurately depict black holes and wormholes. Which won the team at DNEG an Academy Award. My tutorial produces a fairly decent recreation of the wormhole effect and should give you the basic look as I’m sure you could improve upon it.
