Harmony 20's new Pre-render Cache node provides a way to lighten and speed-up the rendering of complex scenes. You can think of it as a simplified Composite node used to store a cache of rendered frames for selected nodes.
This node can be very useful when working on a scene that contains an element that is extremely long to render, such as a 3D model, a complex special effect or even a scene rendered in 4K.
How to connect the Pre-render Cache node
-
Do one of the following:
-
In the Node view, press ENTER and use the quick access drop down to search for and select the Pre-render Cache node.
-
In the Node Library, search for the Pre-render Cache node and drag and drop it into the Node view,
-
-
In the Node view, connect the Pre-render Cache node between the element you want to Pre-render and the composite. You can give each element its own Pre-render Cache node, or give a group of elements a Pre-render Cache node.
-
You can connect as many input images as you want to the Pre-render Cache node.
The Pre-render Cache outputs a bitmap image and, contrary to regular Composite nodes, it does not allow vector effects to travel up its node system. Hence, effects such as the Colour Override or the Apply Peg Transformation effects will not work when connected under a Pre-render Cache node.
Properties of the Pre-render Cache node
The Pre-Render Cache node shares some of its properties with the Composite node. Below is a list of the available Pre-render Cache node properties and their use.
Parameter |
Description |

Enable/Disable |
Allows you to enable or disable the node. When disabled, the node has no visible effect on the rendered image, nor on the preview in the Camera, Perspective, Side and Top views. |
Colour Swatch |
Sets the colour of the layer in the Timeline view, and of the node in the Node view. |
Name |
Allows you to enter a name for the node. |
