Description:
In this tutorial, Asif Ali shows how to create a custom attraction force effect in Unreal Engine Niagara, where particles follow a moving object, creating an impressive visual effect. Inspired by a Unity effect, Asif demonstrates how to use a mesh, emitters, and Niagara parameters to achieve this cool particle attraction effect. The video covers techniques such as controlling particle spawn rates, applying color variations, using vortex rotations, and implementing a point attractor that moves with the object. The tutorial also includes setting up lights and using post-processing for added visual flair.
Key Notes:
- The effect uses a custom attraction force where particles follow a moving object, creating a dynamic visual.
- The attraction force is controlled using the Niagara Point Attractor, which dynamically updates based on the object’s location.
- A GPU particle system is used for the primary effect, with parameters for spawn rate, size, and color variation, including a smooth transition from orange to purple.
- The vortex effect adds rotation to the particles, controlled by the vortex intensity and Z-axis rotation.
- To make the particles follow the object, the user parameter is connected to the object’s location in the blueprint, updating the attractor’s position each frame.
- A post-process effect is used to add lens flare and a dark mask, enhancing the final look of the attraction force.
- Light particles are used to illuminate the scene, emitting light as the attraction effect moves.
- The emitter is duplicated and adjusted for both light and non-light versions, creating variations of the attraction force.

Additional Notes:
This simple yet visually striking effect can be used in a variety of game development scenarios, such as magic forces, gravitational pulls, or other attraction-based mechanics. The principles shown in this tutorial, including working with GPU particles, vortex effects, and dynamic mesh locations, can be adapted to create more complex VFX effects in Unreal Engine. For those new to Niagara, it’s a great way to experiment with basic force fields and attractor systems in a highly customizable environment.
