Syntax

[UCLASS](Programming/UnrealArchitecture/Reference/Classes#classdeclaration)(EditInlineNew, Category="Camera", Meta=(DisplayName="Camera Query"))
class UNiagaraDataInterfaceCamera : public UNiagaraDataInterface

Variables

		Name	Description
	bool	bRequireCurrentFrameData	When this option is disabled, we use the previous frame's data for the camera and issue the simulation early.
	int32	PlayerControllerIndex	This is used to determine which camera position to query for cpu emitters.

Constructors
