UE4 Animate Materials Through Matinee - Not Working

Hi, I’m trying to animate a material instance parameter through matinee using a float material param track, but it’s not working. I tried using a material instance actor, but it seems to want to communicate to an actor in the scene instead of a material instance, so when I select the static mesh, it says static objects cannot have animated materials. I tried to follow the steps in the UDN tutorial to set this up, but nothing’s working. Help?

It looks like this is the way to do it now in UE4:

It works, but not really ideal since you can’t preview the Timeline in the viewport. I wish the old method was still available.
