Syntax

USTRUCT&40;BlueprintType, Meta&61;&40;DisplayName&61;"Mesh Selection"&41;&41;  
struct FGeometryScriptMeshSelection

Remarks

FGeometryScriptMeshSelection is a container for a Mesh Selection used in Geometry Script. The actual selection representation is not exposed to BP, use functions in MeshSelectionFunctions/etc to manipulate the selection.

Internally the selection is stored as a SharedPtr to a FGeometrySelection, which stores a TSet (so unique add and remove are efficient, but the selection cannot be directly indexed without converting to an Array).

Note that the Selection storage is not a UProperty, and is not serialized. FGeometryScriptMeshSelection instances cannot be serialized, they are only transient data structures, that can be created and used Blueprint instances.
