Turn static scenes into dynamic animations — in seconds.

TweenKit is a non-destructive animation toolkit for Blender built to make motion creation faster, more intuitive, and more creative.

Explore 92 ready-to-use animation presets for objects, cameras, lights, text, emissive materials, and meshes. Apply an effect with one click, combine multiple animations, experiment freely, and remove anything you don't need.

Every effect is kept on its own NLA track, giving you the freedom to build complex motion while keeping your original animation safe.

Create. Experiment. Stack. Refine.

🎬 What Can I Animate with TweenKit?

TweenKit is designed to help you quickly add motion to different elements of your Blender scenes.

The current library includes animation presets for:

• 🎭 Objects — Movement, rotation, scaling, bouncing, shaking, and more.

• 📷 Cameras — Dynamic camera movement and cinematic motion.

• 💡 Lights — Animated light movement and visual effects.

• 🔥 Emissive Materials — Dynamic emission and material-based animation.

• 🔤 Text — Animated entrances, exits, and motion effects.

• 🧩 Meshes — Deformation and motion effects for supported geometry.

With 92 ready-to-use presets, TweenKit gives you a flexible starting point for creating everything from subtle motion to more energetic and stylized animation.

🎯 What Can Affect Animation Results?

Animation results can sometimes depend on more than the selected preset or visible settings.

Factors such as:

• Object transforms

• Object scale and origin

• Existing animation data

• NLA track configuration

• Scene frame rate

• Scene frame range

• Blender version

• The selected object or object type

can affect how an animation behaves.

For more consistent results, keep your Blender version, scene settings, object transforms, and animation setup consistent when working across different projects.

This is often related to the object's transform scale.

Before applying TweenKit animations, check the object's transforms and make sure its scale is appropriate for your scene.

If necessary, apply the object's scale:

Object → Apply → Scale

Also make sure your scene uses consistent units and dimensions. Inconsistent object scales or scene units can cause animation effects to behave differently than expected.

If a TweenKit animation doesn't behave as expected, start with these checks.

1. Make sure TweenKit is enabled

Go to:

Edit → Preferences → Add-ons

Search for TweenKit and make sure the add-on is enabled.

2. Check your selected object

Make sure you have the correct object selected before applying an animation.

Some effects may behave differently depending on the type of object or animation data already present.

3. Check the object's transforms

Verify the object's:

• Location
• Rotation
• Scale
• Origin

Inconsistent transforms, especially unapplied scale, can affect how an animation behaves.

If necessary, apply the object's scale:

Object → Apply → Scale

4. Check your existing animation

If the object already contains animation data, make sure the existing animation is valid and behaving correctly.

TweenKit is designed to work alongside existing animation through the NLA system, but unusual or incompatible animation setups may produce unexpected results.

5. Check the NLA tracks

TweenKit effects are stored on their own NLA tracks.

Open the NLA Editor and verify that the TweenKit effect was created correctly.

Check that:

• The TweenKit track exists.
• The NLA strip covers the expected frame range.
• The track or strip has not been muted or disabled.
• The strip is not being affected by another NLA track.

6. Check the timeline and frame range

Make sure the current frame is inside the range where the animation is supposed to play.

Also check the scene's:

• Start frame
• End frame
• Current frame
• Playback range

📍 Animations Behave Differently Than Expected

If an animation appears to move, rotate, or scale incorrectly, check:

• Object transforms
• Object origin
• Object scale
• Existing animation
• NLA tracks
• Scene frame range
• Animation preset settings

Incorrect object origins and transforms can be particularly important for animations involving rotation, movement, or scaling.

Yes. Content generated using TweenKit can be used in your own projects, including commercial projects, subject to the terms of the TweenKit license.

However, you are responsible for checking the licenses of any third-party assets, models, textures, materials, or other resources included in your project.

📦 Can I redistribute TweenKit itself?

No.

The TweenKit addon, its source code, and any included proprietary resources may not be redistributed, resold, or repackaged unless explicitly permitted by the applicable license.

Your license to use TweenKit does not grant permission to distribute the addon itself.

📁 Can I share a Blender file containing TweenKit-generated content?

This depends on the specific license terms and how the Blender file is distributed.

If the file contains only content generated with TweenKit, the generated content may generally be used as part of your own project, subject to the TweenKit license.

If the Blender file also contains the TweenKit addon, proprietary resources, or third-party licensed assets, make sure that distributing the file complies with all applicable licenses.

🎬 Recommended Animation Workflow

A good TweenKit workflow is:

Start Simple → Apply → Preview → Adjust → Stack → Finalize

Avoid applying multiple effects at once before checking how each animation behaves.

Build your animation progressively and add complexity only when necessary.

This makes it easier to understand how each effect contributes to the final result and makes troubleshooting much simpler.

💾 What should I do before applying animations to a complex scene?

Save your Blender file first.

Then:

• Test the animation on a simple object.

• Confirm that the selected preset behaves as expected.

• Check the object's scale and transforms.

• Preview the animation before adding additional effects.

• Verify the NLA tracks created by TweenKit.

• Save a working version of your file.

• Add additional effects gradually.

This makes experimentation safer and gives you a clean version to return to if something doesn't behave as expected.
