Parenting

Parenting links one layer to another so the child follows the parent’s transform. Move the parent and the child moves with it; rotate the parent and the child rotates around the parent’s anchor point.

To set a parent, pick one from the layer’s parent dropdown in the timeline. Or just simply click, drag and connect the dot icon next to the parent dropdown to another layer. The child keeps its own transform values — they’re now relative to the parent, not the composition.

Null layers are especially useful as parents: invisible in the viewport, but they give you a control handle that drives several children at once.
