Reads a value previously stored by Set Variable and emits it on the output. Variables are scoped to a single graph evaluation — they let you stash a value once and reuse it from anywhere downstream without rewiring long cables across the canvas.

​
Configuration

  • Key — the name of the variable to read. Must match the name used by the Set Variable node that wrote it.

​
Tips

  • The input port is ignored — the only way data enters this node is via the matching Set Variable.
  • If nothing has been set under that key, the output is empty.
