Layer Precomp

Method

This node pre-composites a layer so it can be rendered inside another layer. Any exposed values from inside that layer will also be carried over into the new layer.

Attributes

Name Description
Source Layer Select a layer to precomposite.
Render Width / Height Change the width and height of the rendered layer. When set to 0, render width and height are set to scene resolution.
Preview In Viewport Preview the effect blended with alpha in the viewport.
Preview RGB In Viewport Preview the RGB values in the viewport.
Preview Alpha In Viewport Preview the alpha values in the viewport.
Time Mode Change relative time in which the precomped layer is running.
  • Node Relative, Time will be relative to the start and end time of the node.
  • Layer Relative, Time will be relative to the start and end time of the layer.
  • Global, Time will be relative to the start and end time of the project.
  • Use Deltas (Looping), Time will use its own time and run continuously.
Time Offset Offset the start time of the layer.
Playback Speed Speed at which the layer is played at.
Looping Enable or disable the layer from looping at the end.
Loop Start Time Offset the start time of the layer after each loop.
Update Active Enable or disable the layer from re-rendering to the current scene. When disabled, a static image will be output.
Optimise Memory On Idle This will dynamically remove memory data if the node isn’t active. This can optimise memory usage, but can cause issues loading a precomp if it is sufficiently large.
Hide Handles, Bounding Boxes and Range Indicators Toggles the visibility of handles, bounding boxes and range indicators.
