[Closed] update particle flow in vp after its creation?

Hi Folks,

Just having a bit of an annoyance with a particle flow script here where it creates with no issues but doesn’t update in the viewports, in other words I don’t see any particles despite everything being correct in the flow. If I make another particle flow node in the particle view and delete it it updates the viewports fine and i can then see my particles – is there a command I need to use to get pflow to update?

Here’s some max 8 code:

-- make a pf node

fn MakePF particleCount positionObj shapeInst =
(
	
	PF_Source isSelected:on Logo_Size:100 Emitter_Length:100.0 Emitter_Width:100.0  Emitter_Height:0.01 pos:[0.0,0.0,0.0]
	
	-- make operators
	
	particleFlow.BeginEdit()
	
	op1 = Birth()
	op1.Emit_Start = 0
	op1.Emit_Stop = 0
	op1.amount = particleCount
	op2 = Position_Object()
	op2.Emitter_Objects.count = 0
	op2.Emitter_Objects = #(positionObj)
	op3 = Rotation()
	op4 = Shape_Instance()
	op4.Shape_Object = shapeInst
	op5 = RenderParticles()
	op6 = DisplayParticles()
	op6.color = $.wireColor
	
	-- make an event
	
	ev1 = Event()
	
	ev1.SetPViewLocation ($.X_Coord) ($.Y_Coord+100)
	particleFlow.EndEdit()
	
	-- Assign ops to event
	
	ev1.AppendAction op1
	ev1.AppendAction op2
	ev1.AppendAction op3
	ev1.AppendAction op4
	ev1.AppendAction op6
	$.AppendAction op5
	$.AppendInitialActionList ev1

)
