A short tutorial on linking objects and creating
1. Preparing your cut-out character
file in Photoshop. |

2. Import the file in AfterEffects In the project window double-click the composition icon and the new composition is opened. Its resolution is the resolution of the PSD file and the layers are arranged and named the way they were saved in PhotoShop. You can now (or later) change the dimensions of the stage, if you like. 3. Create a hierarchy and adjust the pivot points The principle of parent/ child interactions is that all the transformations (scaling, rotation, position) you apply to the parent affect the children, grand children, etc, but you can transform them independently from the parents and this rule works in only one direction - from the older to the younger generations. Using the chain tool, link the layers in a hierarchy,
according to the rule above. Like that: |

|

| Now
we have to adjust the pivot points, so that the rotations be predictable.
Generally pivots have to be positioned in the joints or in the center of
balance.
To move the pivot points, use the proper tool: Slide the center points to their proper positions like that: |

4. Time to animate Rotate, reposition, scale, using AfterEffects'
tools or the numerical values for the layers and you will see how everything
behaves quite predictably. Here is the timeline for a simple walking animation cycle: |
