An in-depth look that demonstrates how geometry settings and collision cages work in Physics Now! for After Effects.

You could create your simulation-like animation in After Effects, but there are some excellent tools out there that can help too. One of the most predominant is Physics Now! for After Effects. The physics plugin offers a super easy to use workflow along with really tight integrations with After Effects. One of the underlying principles for making simulations with the plugin is understanding how Geometry and Collison cages work.

Physics Now creator Jakob Wagner dives deep into how geometry and collision work in the plugin. The tutorial starts with looking at shape layers in Ae, then covers some advanced topics and techniques when it comes to collision cages.

Physics Now! lets you work with simulations right within After Effects, and it works as if it were a bundled feature rather than a third-party extension. Just tag a layer as dynamic or static. Then hit simulate and watch your simulation playback on your After Effects timeline.
