Group Output

The Group Output node defines the final output of a node group. It determines which values are passed out of the node group to the parent node tree (or to the renderer, in the case of the Compositor).

In the Compositor, this node defines the image result that is sent to the renderer or to image output after rendering.

This node is updated automatically after each evaluation or render, and updates interactively when connected inputs are changed—provided that all inputs are fully evaluated.

Note

If multiple Group Output nodes are present in a node tree, only the active one is used. All others will show a “Unused Output” warning. The active output can be changed in the header of the node.

Inputs

By default, the node has no input sockets. Sockets appear when outputs are defined for the node group in the Group tab of the sidebar (or when dragging a connection onto the blank socket area).

Each input corresponds to a group output socket that can be exposed to the parent node tree.

Note

In the Compositor, only the first image input is used as the final render result. Any additional sockets will be ignored.

Properties

Outputs

This node has no output sockets. Its sole purpose is to define which values leave the node group.
