This asset is a combination of three different visual effect techniques - A texture based moving distortion material effect, a Niagra Particle based distortion Wave effect, and a Niagra Particle based Swarm-Behavior effect. Combined together, the effects look like a black-hole type object emanating gravity waves that control a swarm of particles around it.

NOTE: If you encounter a white screen while viewing the FX_Demo-SwarmB map navigate to the Project Settings, search for and enable, 'Extend Default Luminance Range in Auto Exposure Settings'.
