Un-Precompose

Un-PreCompose Options

Un-PreComposed Layer Prefix

This option will help you see which layers came from the pre-comp. Whatever you put into this textbox will be added to the beginning of each layer that is un-precomposed. If no prefix is desired, just leave the box empty.

Copy Pre-Comp Attributes To Layers

If you have key frames, effects, etc. applied to your pre-comp and want those attribute to be maintained, select this option. Each layer inside will then receive the effects from its parent and will be made a child of a null object that contains the transform attributes. The null object will have the name ||CONTROLLER||.

option will get rid of any attributes that are applied to your pre-comp. Layers inside the pre-comp will maintain their current positions and attributes. You may notice a change in position if your precomp is a different resolution then its parent composition.

Delete Source After Un-Precomposing

If this option is selected, once the pre-comp has been un-precomposed, it will be deleted from the project. This option will not be available if the pre-comp is being used elsewhere in the project. This option will be disabled if the ‘Keep Pre-Comp in Composition’ option is selected.

Keep Pre-Comp in Composition

If this option is selected, the pre-comp will remain in the parent composition after the Un-PreCompose has taken place. The pre-comp will be turned off, but still be a part of the composition. This option will be disabled if the ‘Delete Source After Un-PreComposing’ option is checked

Notes on 'Copy Pre-Comp Attributes to Layers'

Masks are not copied

For the moment, masks applied to your pre-comp will not be copied over to the extracted layers. This may change in the future, so keep a look out for any updates to the plug-in.

Particle layers

If your pre-comp is a 3D layer that contains particle layers, you may get some issues on running the plug-in. Particle layers are usually meant to be applied to 2D layers, but if the parent comp is 3D, every layer inside will be changed to a 3D layer, so you might get some strange results.

Creation of controller layer

For now, the, any transform attributes of the pre-comp are applied to the null object, which then becomes the parent of each extracted layer. If a layer already has a parent, that layer will not be affected.

General Notes

Parenting is maintained within the pre-comp, however if any layers are parented to the pre-comp, that connection will be broken.

If layers inside your pre-comp contain expressions that use random numbers, you may notice a slight change due to random numbers being based on the layer’s index, which may be changed when running an Un-PreCompose.
