Creating a Pre-Compositing Template
You can create your own template for pre-compositing.
To create a template:
1 Import a pre-comp file without specifying a template—see
Pre-Compositing Import on page 302.
If you are creating a render layer template, the render layer composition
contains a number of link nodes to render pass footage compositions.
The render pass anchors are already set on the link nodes—see
Render
Layer Composition Creation
on page 316.
If you are creating a scene template, the scene composition contains a
number of link nodes to render layer compositions. The render layer
anchors are already set on the link nodes—see
Scene Composition
Creation
on page 317.
2 Build the dependency graph.
3 If needed, edit the render pass or layer anchors—see Pre-Compositing
Anchors
on page 308.
4 (Option) Clean up the template by selecting Composition >
Pre-Compositing and one of the clean-up options. When cleaning up the
template, link nodes are reset, their name is changed to match the
anchors, and unused anchors are removed from nodes and output sockets.
5 Provide the pre-comp file (.txcomposition) to the 3D artist as the render
layer template.
Pre-Comp File Creation and Updates
The creation and update of pre-comp files always starts with the scene
compositions, working its way down to the render layers and finally the render
pass compositions.
The scene/layer/pass compositions are named accordingly: <scene anchor>
<camera anchor> <layer anchor> <pass anchor>.
WARNING Renaming compositions will impair the update process.
All nodes, including output nodes, in each type of composition can be
renamed, since node anchors are used to keep track of the topology during
import.
