Niagara VFX System
You can use Niagara in Unreal Engine to create and preview particle effects in real time, such as smoke, lightning, and fluids. Each effect is controlled by a particle system, which includes emitters that generate the particles.
You create particle systems using the Niagara Editor. The Niagara Editor includes a System Overview panel for creating and editing emitters, a Preview viewport, and a Timeline for playing and scrubbing through the preview.
Station Example
In the station, there is a particle effect playing in a loop. Click the center of the effect, then in the Details panel, find the Niagara System Asset. Double-click the preview image to open the Niagara Editor. There are three emitters in the system, which you can edit in the System Overview panel.
Try selecting a property on an emitter and changing it. For example, on the OmnidirectionalBurs emitter, click Spawn Burst Instantaneous. In the Details panel, change the Spawn Count. The Niagara system will re-compile automatically when you change a property.
