First Non Empty

Returns the first non-empty value among all connected inputs. Useful for merging two branches where only one will have a value for a given run.

The First Non-Empty node returns the first input that actually has a value. Connect several inputs and it forwards the first non-empty one, ignoring the rest — useful for providing fallbacks when an upstream branch may be empty. First Non-Empty is partial-input tolerant, making it useful for merging several conditional branches back into one path.
