Animate Hair length Scale in sequencer

Hi, I’m trying to make an effect of “growing hair” from bald in my cinematic for my metahuman, just by increasing “Hair length scale” from 0 to 1. I add keyframes in the Sequencer but this doesnt work at all. I’ve tried different values of LOADbias just in case but no luck…
I’ve tried another method and I’ve created 2 custom events in the metahuman BP:

  • “no-hair” executing “Set Hair Length Scale” with “scale” at 0.0 targeting Hair, Eyebrows, Eyelashes and Fuzz
  • “with-hair” executing “Set Hair Length Scale” with “scale” at 1.0 targeting Hair, Eyebrows, Eyelashes and Fuzz
    When i call this events in the sequencer, that doesnt work too ! ( I add an event trigger track from the metahuman BP track, then add a keyframe, then right-click and bind to the BP-metahuman custom event created previously… 2 keyframes for the 2 custom events)…
    I don’t understand why nothing works…
    Can someone explain how can i achieve my growing hair effect in sequencer ?
    Thank you

Maybe u can try this🤔

1.click the hair length scale and drag your actor into sequence
2. In your actor add the component that have grooming
3. In your component add the groom group desc
4. Select groom group desc

Then u can animate your hair length scale in your sequence
