Pulsing Health Effect Decal

The effect is inspired by and a re-creation of Dirty Bomb's Health Station. The material is a decal, meaning you must apply it to the world through a DecalActor instead unlike a surface material.

Engine Version: 4.7+

Note: There is a jitter bug in 4.8 when the input Radius-pin of the SphereGradient contains a ScalarParameter instead of a static value somewhere in the chain.
