Syntax
UCLASS&40;&41;
class UConstructionPlaneMechanic : public UInteractionMechanic
Remarks
UConstructionPlaneMechanic implements an interaction in which a 3D plane can be positioned using the standard 3D Gizmo, or placed at hit-locations in the existing scene. A grid in the plane can optionally be rendered.
