Introduction:

• “Hello everyone, I’m Asif Ali, and you’re watching CGHOW! Today, I’m going to show you how I created a Niagara particle system using a static mesh. Let’s dive in and see how it’s done. But before we start, don’t forget to subscribe to my YouTube channel and click the bell icon so you never miss a new tutorial.”

Step 1: Setting up the Particle Emitter

• “We’ll begin by right-clicking and choosing to add a Fountain Emitter and a Static Mesh Emitter. Now, I don’t need the fountain for this tutorial, so let’s delete that. We won’t need gravity either, so I’ll turn that off for now.”
• “In the Emitter properties, I’ll adjust the spawn rate to 20 and remove location and velocity settings. Now, I’ve got particles spawning at a single point.”

---

Step 2: Creating the Niagara System

• “Next, let’s create a new Niagara system to make sure our particles are being spawned correctly. We’ll need to drag the system into our scene.”

---

Step 3: Adding a Static Mesh to Emit Particles

• “Now, let’s add some variety. I’ll use a sphere location for particle emission. This will allow the particles to spawn in a spherical pattern.”
• “Let’s pick a static mesh—I’ll go with a character model for this example. As you can see, particles are now emitting from this mesh. You can also adjust the offset, which will determine the direction of the particles relative to the mesh’s surface.”

---

Step 4: Adjusting Particle Behavior

• “You can also adjust the particle count to 2000 to see the full effect. I’m going to leave the particle size as is for now to get a clear view of how the particles interact with the mesh.”
• “To add more control, I’ll use velocity. However, I prefer not to use any initial velocity here since I want the particles to remain static for now. I’ll also turn on some basic animation to add a little life to the particle movement.”

---

Step 5: Applying Texture and Dynamic Color

• “If you want your particles to adopt a color based on the mesh, we need to tweak the material. The particles are using a basic texture now, but they don’t match the mesh’s material. Let’s fix that!”
• “I’ll add a Dynamic Parameter to the material so it can adjust according to the particle’s color. Now, let’s apply the Dynamic Parameter to the mesh. This will make sure that the particles inherit the correct color from the mesh’s texture.”

---

Step 6: Modifying the Particle Material

• “Now, we’ll go into the material editor and duplicate the static mesh material. We’ll use the Dynamic Parameter to adjust the color dynamically for each particle.”
• “After making these changes, you should see the particles taking on the same color as the mesh texture.”

---

Step 7: Fine-Tuning the Particle System

• “I’ll make a few more adjustments—first, let’s add a little more randomness to the particle sizes. I’ll adjust the random range to make the particles look more varied.”
• “Next, I’ll add a sprite facing module so that the particles always face the normal direction of the mesh. This is especially useful for effects where particles need to align to a character’s surface.”

---

Step 8: Adding Light to the Particles

• “To give the particles some extra glow, let’s add a light source. I’ll place it near the particles so you can see how it illuminates them. If the glow is too strong, I’ll adjust the intensity and size of the light.”

---

Step 9: Making Final Adjustments

• “I’ll finish by tweaking the particle size, adjusting gravity, and playing with some noise functions to make the effect feel more natural and dynamic.”
• “You can also add custom parameters like lifetime and speed to give your particles more variation.”

---

Conclusion:

• “And that’s how you create a Niagara particle system using static meshes in Unreal Engine! You can now adjust the parameters and materials to fit your project’s needs.”
