Soft Body turns every contour above it soft in the comp's physics world. Closed shapes squash and wobble; open paths hang as rope. Gravity, walls and other bodies are in Dynamics World.
How to use it
- Select a shape layer (closed shapes for blobs, an open path for rope).
- Choose Geo Ops ▸ Dynamics ▸ Soft Body.
- For a rope, turn on Pin the start and/or Pin the end.
