In the world of motion design, some effects immediately capture attention: organic shapes that follow movement, dynamic masks, graphic elements that react to video, and HUD animations tracked directly to the content.
One of these effects is Blob Tracking, a technique increasingly used in motion graphics, VFX, and visual experimentation, often found in projects created with TouchDesigner.
The good news for motion designers is that this type of workflow can now be explored directly in Adobe After Effects thanks to a new free plugin: AE Blob Tracker.
đ The project is available for free on GitHub:

What is Blob Tracking in Motion Design?
The term Blob Tracking comes from the concept of a âblobâ, meaning a visual shape or area identified inside an image or video.
Unlike traditional motion tracking, where a specific point is followed (such as a corner, a face, or a particular element), blob tracking works with movement regions, recognizing larger and more organic areas.
Basically, the software identifies a visual mass and tracks its:
- Position
- Movement
- Size
- Changes over time
This allows artists to create effects widely used in motion graphics:
- Abstract shapes following people or objects
- Dynamic graphic overlays
- Liquid and organic effects
- Animated data visualizations
- Creative tracking for music videos and commercials
An effect widely used, but often connected to premium plugins
In a professional After Effects workflow, achieving this type of result is not always straightforward.
Many motion designers use commercial plugins or external software to create advanced tracking systems and shape generation workflows.
Professional tracking tools can be expensive, especially for freelancers, students, or artists who are just starting their journey.
For this reason, the availability of a free tool like AE Blob Tracker represents an interesting resource for the creative community.
AE Blob Tracker: a new free tool for After Effects
AE Blob Tracker is an open-source project designed to bring the concept of blob tracking into the Adobe After Effects workflow.
The plugin allows motion designers to experiment with a more creative approach to tracking, transforming video movement into information that can be used to create animations and graphics.
It can be useful for:
- Motion designers
- Art directors
- VFX artists
- Creative coders
- Designers working with generative video
How can it be used in a creative project?
The possibilities are endless.
Imagine having footage of a person walking.
With a blob tracking system, you can create:
- A light trail following body movement
- Geometric shapes reacting to movement
- Liquid or fluid effects connected to the subject
- Graphic elements generated directly from the video
Or you can use it in a more experimental context:
- Music videos
- Interactive installations
- Event visuals
- Brand animations
- Cinematic titles
Why is this type of tool interesting for 3D Artists?
Although it was created for motion design, blob tracking can become a very useful element for artists working in the 3D field.
More and more artists are combining:
- After Effects
- Blender
- Cinema 4D
- Unreal Engine
creating hybrid pipelines between compositing, animation, and 3D rendering.
A tracked movement in After Effects can become the starting point for creating:
- Procedural animations
- Particle effects
- Simulations
- Dynamic controls for 3D scenes

Motion design continues to evolve thanks to increasingly accessible tools.
In the past, effects like these were mainly available through expensive software or premium plugins. Today, thanks to the open-source community, independent artists can experiment with advanced techniques without major investments.
AE Blob Tracker is a small example of how free tools can open new creative possibilities.
If you work with After Effects and want to add a more organic and experimental approach to your projects, it is definitely worth trying.
