Making wall Glow

Hey UE4 Community,

I’m looking for ideas of how I can make a one side of the edge of a wall glow brighter and brighter the closer a player gets, but here the kicker; it needs to be able to be used on multiple buildings of different shapes and sizes. Any advice?

Interfaces do you know them ;):rolleyes:?
Well they need to be blueprints, I think…
Also I am not even sure if interfaces will help on this but maybe an attached actor? That iterates the components and if has skeletal mesh or static mesh do this or that…
With interfaces you can detect easily when an actor gets close and so get special script for the blueprints in question…
I am sure there are a lot of possibilities for this problem, Even a function from GameMode to iterate all static mesh actors…
