constant1 –> blur1 –> transform1 –> dummy. So my dummy is placed below the transform node. Yes, if i want i can get it using .input(0).input(0)…..knob(‘format’) without problem. But this approach is not dynamic, if i insert something between constant1 and transform1 then the code will break. Try to search dir() but still got nothing about it. Anyone can help? or any other idea?
thanx.
