Channels keep track if their owner's(MovieSceneSection) signature change, which we also now invalidate in the FCurveModel::Modify function. InteractiveCurveView on Tick checks and sets a set of values to see if the view or something else has changed and then does a global recreate or checks each curve which then checks that new signature check to see if any individual curve was modified. #jira UE-157989 #preflight 637d3b0c170bc34a93a6e6ab #rb andrew.rodham [CL 23379966 by Mike Zyracki in ue5-main branch]
