Video Title:
GPU vs CPU Particles with Lights in Niagara – Tutorial

Description:
In this tutorial, we continue our Niagara basics series, this time focusing on the difference between GPU and CPU particles and how to add lights to your particle effects. We’ll create a simple particle effect with lights and show you how to use both particle systems efficiently. You’ll learn how to connect particle systems to lights, how to control their intensity, and how to handle large numbers of particles on both the GPU and CPU to ensure smooth performance. Let’s get started!

What We’ll Cover:

• Adding Light to Particles: We’ll go over how to connect lights to your particle system, allowing them to change color based on the particle color.
• Particle Size and Light Intensity: Learn how to adjust the size of the light and its intensity to match your particles, creating visually appealing effects.
• GPU vs CPU Particles: Understand the differences between GPU and CPU particle systems and how they affect performance.
• Handling Large Numbers of Particles: Learn how to increase the number of particles on the GPU without causing lag and performance issues.
• Color Control: How to adjust the color of the particle’s light independently from the particle color, including making the light visible but reducing its intensity.

Key Steps:

• Creating the Particle System: Start by creating a basic particle system and adding a light to it. We will adjust the radius, intensity, and color of the light.
• Using Translucency to Control Light Color: Learn how to make the light take the particle color by enabling translucency and adjusting the alpha to control visibility.
• Switching Between CPU and GPU Particles: We’ll demonstrate how to switch from CPU to GPU particles to see how each handles performance with large numbers of particles.
• Performance Testing: See how increasing the particle count affects performance on both CPU and GPU. Learn the limits of CPU particles and how to switch to GPU particles for better performance with high particle counts.
• Final Comparison: Watch as we increase the particle count and observe how the GPU handles it smoothly even with 50 million particles.

Key Takeaways:

• Lighting and Particles: Learn how to create stunning effects by combining lights with particles in Niagara.
• Efficient Performance: Gain insights into using GPU for handling large numbers of particles and ensuring smooth performance.
• Practical Knowledge: By understanding the strengths and limitations of both CPU and GPU particle systems, you can make informed choices based on your project needs.
• Performance Tips: Get tips on managing performance when dealing with high particle counts and ensuring your system runs efficiently.

Next Steps:
In the next video, we’ll dive into working with Mesh Renderers and how to incorporate them into your Niagara effects for more complex visual effects.
