This will leave the position attribute in the child layer free for a wiggle expression. First number is how many times the clip moves per. This is a huge distinction in the functionality of parenting in After Effects and simply PickWhipping like attributes. Type: wiggle(1,35) to get a good handheld effect (3,55) is a good effect for hand held while running effect.

If you were to parent the two layers together and NOT PickWhip their position values, then everything will behave as expected. The next method may seem like a straight forward and simple concept if you are coming from or are accustom to creating animations in 3D applications, and it may seem like the only clear method to you. Step 17: We have a Graph icon also in wiggle expression to show a graph of wiggle expression parameters. One of the methods to do this is to add the wiggle expression to the anchor point of the child layer rather than the position attribute. Step 16: We can Enable wiggle expression by clicking on this icon of Expression of the Position property. Here, Jonathan Berkey shows us how you are able to add a wiggle expression in After EFfects to the parented layer and have the parent behavior to remain intact. The key is behind the PickWhip in After Effects where PickWhipping an attribute to another attribute such as position will behave like a parent However it is not a parent in its truest form. If you have a parent layer in After Effects with animation applied and a child object that follows the parents position, and you want to create a wiggle expression fro the child layer, You may find that the child will wiggle according to the expression however, it no longer moves with the parent and stays put.
