Pass-through when the input has any dated properties; emits the value wired to Default value when the input is empty. Compensates for upstream nodes that drop to an empty timeline (e.g. an Attribute on a never-populated field, or a Match on an empty input). The legacy graph engine returned false from Match on empty input, so converted graphs splice this node with a Const(false) wired to Default value to keep that semantics explicit.

​
Inputs

  • Data / default in — the upstream timeline.
  • Default value — what to emit when the upstream timeline is empty. Wire any value-producing node (Const, Attribute, AtMoment, etc.).

​
Outputs

  • Result — the upstream timeline if non-empty, otherwise the value from Default value.
