I am following the Pipes HDA tutorial for Unreal Editor and I have my pipes mesh showing up in the Unreal Engine. But when I drop the curve1 node into the Editable field of the Type Properties window and save and reload the HDA in UE4 I have no option to extend the curve as shown in the video tutorial @ 6:08 time code. https://vimeo.com/210679269 [vimeo.com]
Is there some other selection node I have to use to verify my curve is indeed editable inside the Unreal Editor 4.2.1?
