Geo Ops ▸ Dynamics ▸ Make Chain from Path lays rigid links along a shape layer's path. It uses the longest contour, resampled evenly by length. Each link is a box turned along the path. Neighbouring links are pinned where they meet, and the first end is pinned to the comp. The path layer is hidden.
How to use it
- Draw a path on a shape layer and select only that layer.
- Choose Geo Ops ▸ Dynamics ▸ Make Chain from Path. It is one undo step, and a message says how many links were made.
- Play to see the chain hang and swing.
Details
- The menu command makes 12 links, 12 px thick, pinned at the first end only.
- Each link is an ordinary rigid body with pin joints; adjust them in the layer's Dynamics section and in Dynamics World ▸ Joints.
