Retimer doesn't work

[tyFlow]

tySplines need to be retimed independently of the flow that generated them. In the modifier panel within the tySplines settings you'll see retimer settings. If you want your tyFlow and your tySplines to use the same retimer keyframes, you can instance the same controller between them, from the Graph Editor....otherwise just ensure the tySplines retimer settings match the tyFlow retimer settings and everything should stay in sync.
