Is it possible to interpolate wind strength over time?

Hi Guys and Girls,

Is it possible to linearly interpolate the wind directional source component currently?

I’m trying to created a global wind speed float variable which changes over time and in turn sets the value of a wwise RTPC to control my wind blend space. have tried using timelines and event ticks but the variables appear to be static no matter what blueprint configuration I try?

Saw a couple of posts which suggested this might be a bug, is this still a thing?

Cheers in advance.
