Hello,
I have read about the snapping abilities for F-curves, but it seems to be missing something really useful that is present in modelling.
We take it for granted, when in edit mode on a mesh, you can select a whole load of vertices and move them all together BUT STILL be able to snap ONE vertex among that whole load of vertices to something else (increment, vertex on another mesh etc), and all the other vertices in your selection move along with that, preserving the shape of the cluster has between it’s own vertices, albeit at their new overall location.
Similarly, I have a cluster of animation curves and key vertices that I want to duplicate tenfold along (time) and down (value) the Graph Editor’s timeline to create a hopping action for a character that traverses across the floor (each cluster is a hop across the next distance of floor). Each time I duplicate, I need the top vertex of the duplicate cluster to vertically align with bottom vertex of the original cluster and of course have all the other key vertices move in relation, maintaining the overall shape of the curves/vertices. And yet, snapping to value with a whole cluster of points selected makes all the points squish up onto the same value!!
It seems such a basic, common requirement that is so common in 3D animation - to repeat the same curves of movement just over a next region of distance, that surely there MUST be a way to do it?
