void	SetbUseMaterialBackfaceCulling (bool Value)
	When enabled the ribbons renderer will not override how backface culling works depending on shape type, but instad use the material culling mode.
void	SetbUseGeometryNormals (bool Value)
	When enabled the ribbons normals will follow the shape of the geometry rather than being aligned to screen / custom facing.
void	SetbUseGPUInit (bool Value)
	Whether we use the CPU or GPU to generate ribbon geometry for CPU systems. GPU systems will always use a fully GPU initialization pipeline, Will fall back to CPU init when GPU init isn't available.
void	SetbUseConstantFactor (bool Value)
	If checked, use the above constant factor. Otherwise, adaptively select the tessellation factor based on the below parameters.
void	SetbScreenSpaceTessellation (bool Value)
	If checked, use the ribbon's screen space percentage to adaptively adjust the tessellation factor.
void	SetbCastShadows (bool Value)
	When disabled the renderer will not cast shadows. The component controls if shadows are enabled, this flag allows you to disable the renderer casting shadows.
void	SetbEnableAccurateGeometry (bool Value)
	Disables two-sided forced rendering (Will still respect material settings) MultiPlane will double geometry count to have triangles facing both sides. With this off MultiPlane will switch normal direction to face view. 3D Ribbons will render like normal meshes with backface culling enabled.
