Variables

	Name	Description
float	Alpha	Current blend alpha.
float	AlphaInTime	When blending in, alpha proceeds from 0 to 1 over this time
float	AlphaOutTime	When blending out, alpha proceeds from 1 to 0 over this time
uint32: 1	bDebug	If true, enables certain debug visualization features.
uint32: 1	bDisabled	If true, do not apply this modifier to the camera.
uint32: 1	bExclusive	If true, no other modifiers of same priority allowed.
uint32: 1	bPendingDisable	If true, this modifier will disable itself when finished interpolating out.
APlayerCameraMa...	CameraOwner	Camera this object is associated with.
uint8	Priority	Priority value that determines the order in which modifiers are applied.

Functions

	Name	Description
void	AddedToCamera ( APlayerCameraManager* Camera )	Allows any custom initialization. Called immediately after creation.
void	BlueprintModifyCamera ( float DeltaTime, FVector ViewLocation, FRotator ViewRotation, float FOV, FVector& NewViewLocation, FRotator& NewViewRotation, float& NewFOV )	Called per tick that the modifier is active to allow Blueprinted modifiers to modify the camera's transform.
void	BlueprintModifyPostProcess ( float DeltaTime, float& PostProcessBlendWeight, FPostProcessSettings& PostProcessS... )	Called per tick that the modifier is active to allow Blueprinted modifiers to modify the camera's postprocess effects.
void	DisableModifier ( bool bImmediate )	Disables this modifier.
void	EnableModifier()	Enables this modifier.
float	GetTargetAlpha()
AActor *	GetViewTarget()
UWorld *	GetWorld()
bool	IsDisabled()
bool	ModifyCamera ( float DeltaTime, FMinimalViewInfo& InOutPOV )	Directly modifies variables in the owning camera
void	ModifyCamera ( float DeltaTime, FVector ViewLocation, FRotator ViewRotation, float FOV, FVector& NewViewLocation, FRotator& NewViewRotation, float& NewFOV )	Allows modifying the camera in native code.
void	ModifyPostProcess ( float DeltaTime, float& PostProcessBlendWeight, FPostProcessSettings& PostProcessS... )	Allows modifying the post process in native code.
bool	ProcessViewRotation ( AActor* ViewTarget, float DeltaTime, FRotator& OutViewRotation, FRotator& OutDeltaRot )	Called to give modifiers a chance to adjust view rotation updates before they are applied.
void	ToggleModifier()	Toggled disabled/enabled state of this modifier.
void	UpdateAlpha ( float DeltaTime )	Responsible for updating alpha blend value.
