Question Animated scar texture effect?

I'm trying to animate a character's skin texture so that it scars when and where it gets damage. I've worked out the scar texture variables on Substance Designer, but I'm still figuring out how to call the texture in Unity and fit the shape/size of the scar to the damage. Can anyone give me a hint?

 

Animating, not sure
Adding it on a position, I've used this asset at my internship I think (there also is an open source decal for skinned mesh asset):

There can be several methods. You can easily search them on Youtube.

For example:

But watch out, greater resolution would result with greater performance cost. I know you'd like it to look just like in Substance Painter, but lower your res depending on your needs.
