How make a material instance change to another by Matinee

Hi there!

I’m Unreal Engine 3 my teacher show me that was possible make a material istance change to another instance by matinne…using this example:

The player has a fire gun and when he attack a wooden crate…she start to take fire and gradually…change the wood material by his instance…a burned wood material…

I want to make this in Unreal 4…but i don’t know how i can do this…If there is another way to do this without the matinee…great…but i still want to know the other way…

Thanks for any help :slight_smile:
