The graph as text

Undo Construction (Async) (latent function)
- In Token (OrreryTerrainUndoToken): not connected
- In Timeout (Float): 30.0
- Then: not connected
- On Completed: not connected
- On Failed: not connected
- Out Result (OrreryTerrainCommitResult): not connected
- Out Reason (EOrreryTerrainAsyncFailure): not connected

Pin	Type	Default	Meaning
Exec in	Exec	—	Runs the node.
Token	Orrery Terrain Undo Token	—	The undo token of a commit (`FOrreryTerrainCommitResult::Undo`), or of an undo to redo it.
Timeout	Float	`30.0`	Real seconds before `OnFailed(Timeout)`; 0 waits for ever.

Pin	Type	Meaning
Exec out	Exec	Runs next.
On Completed	Exec	Fires with the result; Undo is the inverse.
On Failed	Exec	Fires when the node gives up, with Reason; Result is the refused undo (bOk false), its Reason text says why.
Result	Orrery Terrain Commit Result	—
Reason	EOrreryTerrainAsyncFailure	—

How this page is made

Drawn from the C++ declaration’s reflection specifiers, not exported from the editor. Hidden pins, which the editor fills itself: WorldContextObject.

WorldContextObject is the world context: hidden where the Blueprint has a world, shown in one without (a function library)
async action: one exec output per event dispatcher of the action class, and their parameters as data outputs
