Cartoon Material Pulse

Hi folks,
I am trying to think of a way to make a pulsing cartoon like outline for any given object in my game.

I am happy to make the object itself emissive with a material, but what I am looking to do is a bit like the target objective highlighting in Simpsons Hit and Run (see image)

So here the door, when a target, gets a big cartoon style blue corona (for want of a better word). In my game, the target could be any 3d asset so don’t want to hand animate anything to a specific shape.

I have tried to use emissive properties but that gives me a hazy glow and not the cartoon effect I am thinking of.

any one with any ideas? :pray:

may not be perfect, but came up with quite a simple solution:

It wont outline the object, but this will create a bouncing burst effect which I can just add as an object to the mesh which I can enable or disable as I need to
