Fire effects are a staple in motion graphics and visual effects. With Adobe After Effects, you can create highly realistic fire effects using procedural animation techniques. This guide will walk you through the process of generating fire using fractal noise, displacement maps, and other built-in After Effects tools.
By the end of this tutorial, you’ll be able to create a dynamic, customizable fire effect that can be applied to text, logos, or shapes. Let’s dive into After Effects and start creating!
Step 1: Setting Up the Composition
- Open Adobe After Effects and create a new composition:
- Resolution: HD (1920×1080)
- Frame Rate: 24 fps
- Duration: 6 seconds
- Add a black solid background:
- Go to
Layer
>New
>Solid
. - Set the color to black.
- Click OK.
- Go to
- Create a source layer:
- Add a text layer or import a logo.
- Ensure it is white against the black background.
- Rename the layer to
Source
.
Step 2: Creating the Base Fire Using Fractal Noise
- Create a new solid layer:
- Name it
Fractal Flames
. - Apply the Fractal Noise effect (
Effect
>Noise & Grain
>Fractal Noise
).
- Name it
- Modify the Fractal Noise settings:
- Fractal Type:
Dynamic
- Invert:
Checked
- Contrast: Increase slightly
- Offset Turbulence: Animate to move upwards
- Fractal Type:
- Animate the Evolution:
- Set a keyframe at 0 seconds (
Evolution = 0
). - At the end of the timeline, set Evolution to 3 full rotations.
- Set a keyframe at 0 seconds (
- Pre-compose the Fractal Flames layer:
Right-click
>Pre-compose
.- Select
Move all attributes into the new composition
. - Name it
Fractal Flames Comp
.
Step 3: Applying Displacement and Blur Effects
- Select the
Source
layer. - Apply the Displacement Map effect (
Effect
>Distort
>Displacement Map
).- Set the
Displacement Map Layer
toFractal Flames Comp
. - Adjust Horizontal Displacement:
3
. - Adjust Vertical Displacement:
6
.
- Set the
- Apply the Compound Blur effect (
Effect
>Blur & Sharpen
>Compound Blur
).- Set the
Blur Map
toFractal Flames Comp
. - Increase
Maximum Blur
to4
.
- Set the
Step 4: Creating Fire Motion and Distortion
- Add an Adjustment Layer (
Layer
>New
>Adjustment Layer
).- Name it
Inversion
.
- Name it
- Apply Gaussian Blur (
Effect
>Blur & Sharpen
>Gaussian Blur
).- Set
Blur Amount
to50
.
- Set
- Change the Blending Mode to
Exclusion
. - Apply CC Vector Blur (
Effect
>Blur & Sharpen
>CC Vector Blur
).- Blur Type:
Direction Fading
- Set
Amount
to140
. - Set
Angle
to180
.
- Blur Type:
- Apply Turbulent Displace (
Effect
>Distort
>Turbulent Displace
).- Displacement:
Twist Smoother
- Amount:
20
- Complexity:
7
- Animate
Offset
upwards over time.
- Displacement:
Step 5: Adding Additional Texture and Depth
- Create a new solid layer (
Layer
>New
>Solid
).- Name it
Overlay
.
- Name it
- Apply Gradient Ramp (
Effect
>Generate
>Gradient Ramp
).- Swap the colors to create a dark-to-light gradient.
- Apply Fractal Noise (
Effect
>Noise & Grain
>Fractal Noise
).- Fractal Type:
Dynamic
- Invert:
Checked
- Contrast:
150
- Scale:
200
- Animate
Offset Turbulence
to move upwards.
- Fractal Type:
- Apply a second Fractal Noise effect:
- Scale:
9
- Animate Evolution (
5 full rotations
over 6 seconds). - Set
Blending Mode
toAdd
.
- Scale:
- Apply Turbulent Displace again:
- Size:
30
- Animate
Offset
upwards. - Set
Blending Mode
of the layer toOverlay
.
- Size:
Step 6: Colorizing the Fire
- Create an Adjustment Layer (
Layer
>New
>Adjustment Layer
).- Name it
Colorize
.
- Name it
- Apply Levels (
Effect
>Color Correction
>Levels
).- Adjust
Input and Output
values to increase contrast.
- Adjust
- Apply Color Balance (HLS) (
Effect
>Color Correction
>Color Balance (HLS)
).- Adjust Hue towards orange/red.
- Increase Lightness slightly.
- Apply Glow (
Effect
>Stylize
>Glow
).- Adjust Glow Radius and Glow Intensity for a natural fire glow.
Step 7: Final Touches and Rendering
- Preview the animation to check the motion and color.
- Adjust the keyframes if needed to refine the effect.
- Render the final output:
- Go to
Composition
>Add to Render Queue
. - Choose
Format: H.264
for a lightweight video. - Click
Render
.
- Go to
Conclusion
With these steps, you’ve created a dynamic and realistic fire effect in Adobe After Effects using procedural animation techniques. The flexibility of this method allows you to apply it to various elements like text, logos, or footage. Experiment with different settings to achieve unique fire styles, and don’t hesitate to add your creative touch!
