Blender | 3D Dissolve Effect Using Particles
- Blender
I want to create a dynamic disappearing effect for a 3D object using particles, like the dissolve effects often seen in VFX.
Prerequisite: Blender v4.0.2
1. Add a Text Object
Set up the text object however you like.
Once you’ve finished setting it up, right-click and convert it to a Mesh.
2. Configure the Particle Settings
1｜Add a Particle System
Click the “+” on the right to add it.
2｜Configure the Particle Values
□ Emission
Number: 10000
Frame Start: 0
Frame End: 0
Lifetime: 200
Source > Distribution: Random
With this, if you play it once, you’ll see large particles falling downward.
□ Velocity
Normal: 0
→ This removes the particles’ initial motion.
□ Field Weights
Gravity: 0
→ This removes the effect of gravity.
3｜Add the Object That Becomes the Particles
□ Add an Object
Add an Ico Sphere via shift + a.
Configure the Particle Settings
In the particle settings, choose the Ico Sphere from the Render settings.
At this point, adjust the object’s Scale value and its randomness.
This time, I’ll use the following values:
Scale: 0.1
Scale Randomness: 0.2
Uncheck Show Emitter in Viewport Display to hide the text object the particles are assigned to.
Configure the Particle Material
Set up the material however you like.
4｜Add a Force Field
Add Turbulence via shift + a.
Adjust the parameters as follows from Physics.
▼ Settings ▼
Strength: 6
Global: ✅
→ This applies the animation across the entire global space.
▼ Falloff ▼
Max Distance: ✅ → 0.8
Setting the Falloff’s max distance lets you animate based on the force field’s position.
5. Animate the Force Field
Move it to the right side of the text and insert a keyframe for Location.
Next, move it all the way to the left and insert another Location keyframe there.
When you play it back, you can see the particles animate in order from the right.
6. Add Wind
If you render it as is, some particle elements will remain, so let’s add Wind to blow them away completely.
Add Wind via shift + a.
□ Configure the Parameters
▼ Settings ▼
Strength: 4.0
▼ Falloff ▼
Shape: Tube
Max Distance: 0.8 (matched to the Turbulence setting)
▼ Radial ▼
Max Distance: 0.8 (matched to the Turbulence setting)
Playing it back as is, I could see the area affected by Wind rotating on the X-axis and flying up into the sky.
□ Build a Parent Relationship with the Turbulence
In Object Properties, under Relations, set the Parent to the Turbulence object.
Playing it back in this state makes it fly straight up, so let’s adjust the Transform values a bit.
7. Rendering
Adjust the particle settings on the text object.
Uncheck Render > Show Emitter.
This way, the text object won’t appear when rendered, and only the particles will show up in the render result.
Next, bake the particle simulation results.
