Hi, I am unsure if this is a problem with AnimationControllerComponent or VehicleAnimationComponent but I've added a new variable to my vehicle animation workspace and everything previews correctly. I've now tried to add control to this variable via my script. I've successfully retrieved the animation index and then set my variable value using VehicleAnimationComponent::SetFloatValue(), but do not see any effect in-game.
Here is a video showing my animation workspace, and scripts which control the animation:
