Layer Image

Brief Description

The Layer Image returns a reference of an image of a specific layer (if in Source or Source With Modifiers mode) or the given layer blended with the rest of the Composition below if in Post Blend mode. This is useful to duplicate an element without making a hard-copy of it but just referring to the element so that if anything changes in the source, it is reflected in the copy.

If the blend mode of the layer that uses the Layer Image is set to replace and the Layer Image Which parameter is set to Post-Blend, this will act as an Adjustement Layer to everything below in the Composition stack.

N.B: When set in Post-Blend mode, the Layer Image can only reference layers that are below in the Composition, otherwise this would create a cyclic dependency and Autograph will prevent you to do so.

Referencing 3D layers

The Layer Image is also able to reference a 3D layer. If the referenced layer is a 3D layer, a new render of the 3D scene to which the 3D layer belongs to will be performed, unless Use Existing 3D render is checked. Launching a new 3D render is very useful to extract other render passes of a scene (such as the Z depth) or to render it with a different format.
