Variables

  Type Name Description
Public variable TArray< FFloatCurve > FloatCurves  
Public variable TArray< FTransformCurve > TransformCurves : TransformCurves are used to edit additive animation in editor.
Public variable TArray< FVectorCurve > VectorCurves : Currently VectorCurves are not evaluated or used for anything else but transient data for modifying bone track Note that it doesn't have UPROPERTY tag yet.

Functions
