Enums[edit]

EViewTargetBlendFunction[edit]

VTBlend_Linear 
Camera does a simple linear interpolation.
VTBlend_Cubic 
Camera has a slight ease in and ease out, but amount of ease cannot be tweaked.
VTBlend_EaseIn 
Camera immediately accelerates, but smoothly decelerates into the target. Ease amount controlled by BlendExp.
VTBlend_EaseOut 
Camera smoothly accelerates, but does not decelerate into the target. Ease amount controlled by BlendExp.
VTBlend_EaseInOut 
Camera smoothly accelerates and decelerates. Ease amount controlled by BlendExp.

Structs[edit]
