Heart Attack Effect Tutorial in Unreal Engine Niagara

In this tutorial, I’ll walk you through the creation of the Heart Attack Effect, where we simulate a heart bulging, hitting the ground, and then bursting into heart-shaped particles. The effect also includes glowing flashes, streaks, and various dynamic behaviors, all made using Unreal Engine’s Niagara system. Let’s break it down!

Key Points:

• Initial Heart Emitter:
• The effect starts with a heart-shaped mesh that bulges using a world offset in the material.
• The bulging animation is controlled by a dynamic parameter, making the heart grow larger and shrink.
• The heart spawns with a constant life span, red color, and scaling animation that pulsates up and down.
• Falling Heart:
• After the heart bulges, it falls to the ground with a delay to match the bulging animation.
• Gravity is applied to the falling heart, and it has a randomized rotation and position for variation in the fall.
• When the heart hits the ground, particles burst out in all directions.
• Impact Heart Ring:
• Upon impact with the ground, the heart ring emits bulging heart particles with random sizes and colors.
• The particles have a random rotation, a velocity applied in all axes, and gravity to give the effect more realism.
• Ground Flash and Decals:
• The flash on the ground is created using a planar mesh and a simple texture that simulates the initial heart burst.
• The decal applied after the flash uses a glowing edge effect created by eroding the texture. This adds a glowing, radiant ring around the flash.
• The material used for the decal animates using dynamic parameters to create the glow effect.
• Ring and Glow Effects:
• A ring texture (created in Photoshop with the smudge tool) is used to simulate the glowing ring effect.
• The ring is scaled and animated over time, with an offset for the texture’s position.
• Heart Shaped Particles and Streaks:
• Several heart-shaped particles are spawned with random lifespans, rotations, and colors.
• Streak effects are applied, with stretching on the Y-axis and random particle sizes to create a dynamic flow.
• The particles are affected by gravity, making them fall to the ground naturally. Additionally, collisions are enabled for these particles.
• Streaks and Strikes:
• The strikes are designed using race textures and particles that are stretched and spread in various directions.
• Slower spawn rates and longer particles make the strikes appear more dramatic as they fade away.
• Customization Tips:
• You can change the color, life span, and scaling animations to create variations of the effect.
• Experiment with textures in Photoshop to create your own for rings and streaks.
• Adjust gravity and velocity values to tweak the falling and bursting behavior to fit your needs.

Final Thoughts:

This Heart Attack Effect is a combination of bulging heart animations, ground impact bursts, and glowing particles. By using the Niagara system, we can create a dynamic and customizable visual effect suitable for many types of scenes, from fantasy to action-packed games.
