Precomposing layers places them in a new composition (sometimes called a precomposition), which replaces the layers in the original composition. Precomposing a single layer is useful for adding transform properties to a layer and influencing the order in which elements of a composition are rendered.

What is PreCompose in AE?

Precomposing simply means taking one or more layers that are already in a composition and turning them into a composition of their own.

Can I undo PreCompose in after effects?

Open the folder that corresponds with your operating system and version of After Effects. ... After Effects must be started after the plug-in has been installed, otherwise it will not show up. If After Effects was open, just restart it. Un-PreCompose will show up at the bottom of the 'Layer' menu.
