Hi guys in this tutorial you will learn how to make mesh based laser beam effect in unreal engine Niagara and also how to use is as laser shooting from one position to any direction you want through blueprint.
This video tutorial breaks down how to create a laser beam effect in Unreal Engine using Niagara. The instructor discusses the blueprint setup, material creation, and particle system setup for the laser beam, impact effects, and related visual elements. Here’s a breakdown of the key points covered in the tutorial:
Blueprint Setup:
Camera and Mouse Interaction:
The camera is tracked and repositioned based on the mouse’s movement.
The start and endpoint of the laser beam are dynamically linked to the mouse position.
Line Trace and Collision:
A line trace calculates the beam’s collision point by tracing from the camera position to the mouse pointer.
The impact point is used to spawn particles and decals.
Emitter Location and Rotation:
Particle emitters for the beam, smoke, and impact effects are placed based on the collision point and adjusted each frame for dynamic effects.
Effect Setup:
Laser Beam:
The beam emitter uses a twisted cylindrical shape with a noise texture to create the beam’s appearance.
A simple material is used for the beam with an option to adjust color and opacity.
Impact and Smoke Effects:
Decals are spawned at the impact point using a combination of black and purple textures that fade out over time.
Smoke and spark effects are added, with materials set to transition colors and opacity based on impact.
Particle Effects:
The energy ball, flashes, sparks, and distortion effects are generated with specific properties, like random size, velocity, and rotation.
The particles are adjusted using sine wave patterns for scaling and noise for randomness.
Material and Textures:
The smoke uses default textures and settings for transparency and fade effects.
Different textures and opacity masks are applied to various particles for the impact, sparks, and fire effects.
Additional Effects:
The instructor adds a range of visual effects, such as distortion, glow, and fire, all linked to the mouse’s interaction with the environment.
Conclusion:
The instructor provides an in-depth explanation of each part of the effect and the necessary steps to replicate it. They also mention that future tutorials may explore variations of the laser beam effect.

Key Bullet Points:
Blueprint setup: Tracking camera, line trace for laser start/end points, and mouse interaction.
Emitter location and rotation: Adjusting emitter positions and rotations dynamically.
Laser beam and impact effects: Creating glowing beams with decals and impact effects.
Particle and texture setup: Using random size, velocity, and rotation for dynamic particles.
Material setup: Employing opacity masks and color transitions for realistic effects.
