Functions
void	SetbCullWhenNotRendered (bool Value)
	Controls whether we cull when not rendered. This includes all reasons for being not rendered such as view frustum, occlusion and hidden flags etc. As this requires feedback form the rendering system, it cannot be used for pre-culling.
void	SetbCullByViewFrustum (bool Value)
	Controls whether view frustum culling is enabled. Niagara can do it's own separate view frustum culling to give coarse visibility culling that does not depend directly on rendering like CullWhenNotRendered. This requires fixed bounds to be used in pre-culling.
void	SetbAllowPreCullingByViewFrustum (bool Value)
	If true and bCullByViewFrustum is enabled, we allow view frustum checks in pre-culling. Meaning we can cull off screen systems before they even spawn.

Public Attributes
Scalability
float32	MaxTimeWithoutRender
	Effects will be culled if they go longer than this time without being rendered.
float32	MaxTimeOutsideViewFrustum
	Effects will be culled if they go longer than this time outside the view frustum.
