Animated Decal from hit impact

I would like to animate a decal created from a weapon impact. The current decal I’m using is from the shooter game I believe. It just has a control for fade time, then when that is up it pops off. I would like to have a hot scorch mark that cools off, then after the fade time is up it will fade off smoothly. In my searches I can only find actor decal info.

Any help is appreciated.

Thx
