Group Out

The “exit” node you place inside a group. From the inside it is a sink with an In; from the outside one output port appears on the Group node. Whatever you connect inside is returned straight to the outside.

• The text field on the node (label, default Out) becomes the name of the port exposed on the outside
• Unlike Group In, you do not pick the type. The moment you connect something to In it takes on that type, which is propagated to the outer output port. Remove what was connected and the type returns to Any
• In is limited to one connection (so that disconnection and muting are reliably propagated to the outside)

When In is disconnected or muted, null flows to the outer output. This keeps an old RenderTexture from lingering downstream in the parent graph.
