A pre-compositing template is a Composite composition, a .txcomposition file. There are three types of templates: layer, scene, and merged. A template contains an arbitrary number of anchor link nodes that source an arbitrary dependency graph.

The anchor link nodes in a template can be unconnected or linked to existing compositions; the link is simply replaced when the template is used to create a composition.

A template has at least one output (the primary) which is typically the final look of the render layer or scene. However, you can add an arbitrary number of secondary outputs to the template.
