i forget if this exists and i simply cant remember how to access it or if im mistaking it for something else and it does not exist
just a graph editor to adjust the speed/ impact of a deformer from point A to B if that makes sense!
nd this is specifically for parameters not for the animation mode

The only thing I can think of similar is the blend shape weight graph, I never heard of graph that would change the "speed"

if we talk about speed the only think it cames to mind are physics 🤔

Yeah, I think you probably misremembering something, do you have an example to what it was used for? Or where you saw it?

Ya im probably misremembering honestly!!! I suppose speed isnt the best way to describe it, but; whereas a deformer will take the fastest way to get from one keypoint to another, sometimes smushing the artmesh in an undesierable path, and a rotation tool will maintain its structure all the way through, but i couldnt remember if there was an linegraph for deformers/params that would help them maintain their structure and not smush together
