Static Mesh Sampling in UE5 Niagara Tutorial | Download Files
hi, guys in this tutorial I will recreate static mesh sampling fx from epic’s content example file in ue5 from scratch so you will have a better understating of how to transfer particles from one mesh to another with normal orientation and color f mesh.

Intro
Hello guys, I’m Asif Ali, and you’re watching CGHOW. In today’s video, I’ll be creating this effect from scratch in Unreal Engine 5 using Niagara. Although this project is available in the Epic content example for Unreal Engine 4.27, I’m going to build it in UE5 so you’ll have a better understanding of how everything works. Let’s dive in and get started! [Music]
Call to Action

Step 1: Setting Up the Project
So, I have Unreal Engine 5 open here with an empty project. First, let’s import the meshes I’ll be using for this effect:
- A sphere
- A torus
- A cone
I’ve already created these meshes in Maya and exported them. Now, I’ll import them into Unreal.
Step 2: Create the Niagara System
Next, I’ll create a new Niagara system by right-clicking and choosing Niagara System > Fountain. This will be my basic starting point. I’ll delete the sprite and the loop modules, as they’re not needed.
Now, let’s add a Mesh Renderer and assign the torus mesh. To see the particles, I’ll adjust the size to 5, and now we can see the torus particles.
Step 3: Add Material for Color
To add color to the particles, I’ll create a basic material called m_con. I’m using a Particle Color node and connecting it to both Emissive Color and Base Color. I’ll override the material in the mesh renderer, and set the color to red so it’s clearly visible.
Step 4: Particle Position and Movement
Now, I want the particles to spawn at the sphere’s position and then move to the torus. So, I’ll use the Static Mesh Location for both the sphere and the torus. I’ll randomize their positions using the Tri Position node for each mesh.
After that, I’ll connect the sphere and torus positions with the particles, and make a Lerp to smoothly transition the particles from the sphere to the torus. I’ll also add a curve to control the transition time.
Step 5: Setting Particle Orientation
At this point, the particles are still not oriented correctly. To fix that, I’ll grab the normal vectors from both the sphere and torus. Using a Lerp, I’ll blend between the sphere and torus normals. This will allow the particles to rotate based on the mesh orientation.
Step 6: Adding Vertex Colors to Meshes
To handle color transitions, I’ll apply vertex colors to the meshes. For this, I’ll paint the sphere and torus meshes using Paint Vertex Color in Maya. I’ll give the sphere a mix of green, yellow, and red, and the torus a blue color.
After exporting the meshes again, I’ll make sure to replace the vertex color information in Unreal’s mesh settings.
Step 7: Apply Vertex Color to Particles
Now, I’ll connect the Vertex Color node in the material to the particle system. I’ll use Lerp to interpolate between the sphere’s and torus’ vertex colors. This ensures that as the particles move, they transition smoothly from one color to the next.
Step 8: Adding Additional Effects
To enhance the effect, I can also randomize the scale of the particles and animate them. For example, I can add randomness to the Z scale using a Random Float range. I can make the particles scale between 0.2 and 2 to give it a more dynamic look.
Step 9: Final Tweaks and Save
Once I’m happy with the effect, I’ll save the project. I’ll also upload this file to my Patreon for you to download if you want to try making changes yourself.
