Anim Notify State: Total Duration vs Frame Delta Time

Development Programming & Scripting C++

I’m trying to make an anim notify state that will lerp the alpha of hand IK on over the duration of the notify state. An anim notify state gives you Notify Begin which has Total Duration and Notify Tick, which has FrameDeltaTime

I’m printing Total Duration and FrameDeltaTime to the screen and so far, Total Duration is a much larger float value than the amount of time that accumulates in Notify Tick. I need a value I can use for the lerp that is the exact length of time of the Notify State. Any ideas on how I get that? Why is Total Duration the wrong number?

I think the total duration includes any playrate speed adjustments. So, if you have a 1.0 second animation but your anim play rate is at 0.5, the total duration would be 2.0.
Frame Delta Time is only the amount of elapsed time since the last tick.
