MapNodeVariableMetaData

For each node in MapNodeVisitations, record the start index and end index of variables added within the body of the node, i.e. a Get node will record just the values it pulls out directly.

Syntax

TArray< TTuple< uint32, uint32 > > MapNodeVariableMetaData

Remarks

For each node in MapNodeVisitations, record the start index and end index of variables added within the body of the node, i.e. a Get node will record just the values it pulls out directly. A function call, however, will record all sub-graph traversals.
