Generally to get ability to edit the spline on Unity , I assign the curve on editable nodes on HDA. But if I want to the spline to be editable on an Input of a Toggle or Button from HDA, how I can I do It??? Is it possible through that way ? or is there any other possible to achive that? Because as soon as I assign the node on Editable node on HDA, I get the Spline visible on Unity. But I dont want in that way, I want the spline to be visible on Unity after i give input in form of either as Button form or as a Toggle.
