Description
Find Intersections for After Effects

Find every intersection
Even through
Shape Layer operators

Trim Paths Repeater Merge Paths Offset Paths Round Corners Zig Zag Pucker & Bloat Twist Everything except Wiggle

Your operators reshape paths at render time, and no plugin could ever see the result. This one can. Find Intersections computes the exact geometry on your screen, finds every point where it crosses, and renders any layers you choose right there. Live, on every frame, while everything animates.

Intersections through Shape Layer operators

Drop the effect on your artwork
Every intersection appears

No setup. Use All Paths is on by default: apply the effect, and every crossing in your artwork is already found (or pick specific paths).

Apply the plugin and every intersection appears

Paths from anywhere in your comp

Mix mask paths on solids, paths on shape layers, parametric ellipses, rectangles and polystars, all pulled from different layers at once. Every layer’s transform is followed automatically. Selecting the layers is the entire setup: no parenting, no expressions.

Paths from multiple layers

Any layer, rendered
at every crossing

Pick up to 5 layers. Cycle them in order or shuffle them with a seed. Scale them with one slider. That’s it. They live at the intersections now, and they follow every move your paths make. Even their rotation can follow the crossing’s angle.

Layers rendered at every crossing

The details

  Self-intersections
Finds where a path crosses itself.

  Use All Paths
On by default. Apply, select layers, done.

  Stackable
Chain multiple instances of the effect on one layer.

  Adjustment layer friendly
Run it above your artwork, non-destructive.

  Grow Bounds
Render past the layer edge with one slider.

  Dots mode
No instance layers? Crossings become clean, colorable markers.

  Rotation modes
Aim instances with Crossing Bisector, Fixed, Random or Path Direction.

Under the hood, intersections are solved from the true bezier geometry of your paths, to sub-pixel accuracy, in milliseconds per frame.
