Video Title:
Creating Glowy Edge Effect with Particles in UE5 Niagara | Tutorial

Video Description:
Hi guys, I’m Ashif Ali, and you’re watching CGHOW. In today’s tutorial, I’ll be showing you how to create a simple yet cool effect where a glowing edge appears at the intersection of a sphere with the scene. This is a particle-heavy effect, so it might not be ideal for games but it’s a great learning experience! If you haven’t subscribed to my YouTube channel yet, please do! Like, share, and comment if you found this video helpful. Let’s jump right into it!

Key Points (in bold):

• Creating the Glowing Edge Material: Use a basic material with transparency and adjust it to create glowing edges on the sphere. Apply the material to the sphere to achieve the intersecting glow effect.
• Setting Up the Niagara Effect: Create a Niagara particle system, and use a sphere mesh for the particles. Customize the particle spawn settings and apply the glowing material to achieve the intersecting particle effect.
• Particle Velocity and Size: Adjust the velocity and size of the particles to control how they spread and interact with the sphere’s surface. Set the velocity to control the speed of the particles as they move away from the sphere.
• Using GPU Simulation for Particle Count: Increase the particle count to simulate a dense particle system, and enable GPU simulation for better performance with a higher number of particles.
• Using Kill Volume for Particle Collision: Add a kill volume around the sphere, so that particles outside the range are removed. This ensures particles only appear on the surface of the sphere.
• Conditional Color Change on Collision: Set up a color condition based on particle collision. Particles will turn green when colliding with the sphere and red when not, allowing for a clear distinction between active and inactive particles.
• Optimizing Particle Appearance: Adjust the spawn rate and color settings for more control over the effect’s look. Use transparency for non-colliding particles and make colliding particles more prominent.

Additional Notes:

• Particle-Heavy Effect: While this effect is visually stunning, be cautious of the heavy particle usage if you’re implementing this in real-time applications, as it may affect performance.
• Customization Options: You can experiment with different particle colors and sizes for unique variations of the effect. The use of collision-based color changes makes it visually dynamic.
• Performance Considerations: If you plan to use this effect in games, consider optimizing the particle count or switching to less resource-intensive methods for large-scale use.
