The animation feature allows you to upload animated 3D files and have them play on Sketchfab.
Uploading animation files
- Solid animation: translation, scale, rotation
- Skeleton-based animation: model rigged with bones
- Morph targets: transformed vertices
In general, you can export your scene as FBX with baked animations (or BLEND for Blender). However, FBX export options will be different across software. Here are some software-specific tutorials from our community:

Viewing animated 3D models
If a model has animations, you can see the animation icon in gallery pages:
When viewing the model page or embedded model, you will see a timeline and animation menus.
For details, see Interface and Options.
Editing animated 3D models
You cannot edit or create animations on Sketchfab, but you can edit some animation properties. See Animation Settings.
Annotations + Animation
Annotations are compatible with animations. They will stick to and follow the model.
Timeframe (Stop Motion)
It's possible to use multiple model files to create a stop motion animation. You just need to include all the models and a special "sketchfab.timeframe" text file.
For a more detailed tutorial, visit the blog.
In this example, there are 3 models:
Specify a duration (in seconds) for each model, in order:
0.5 sphere.obj 0.5 cube.obj 0.5 cylinder.obj
You can download this example file here, and open it in any plain text editor.
Upload them all together, and here's the result:
You can combine multiple files in a single frame using syntax like this:
You can perform translation, rotation, and scale transformations objects using syntax like this:
- @t= to specify a translation followed by the vector components separated by commas, with no extra space
- @r= to specify a rotation followed by rotation angles (in degrees)
- @s= to specify a scale followed by either a single value for uniform scale or a scale vector
- @m=m1,m2,...,m16 to specific a full 4x4 matrix transform
- All of the models must be loaded in the same scene simultaneously, so it can hurt performance if you have many frames with complex models.
- You can use any combination of supported formats, but materials may not be processed correctly if they are not all the same.
- Blender, KSP, Minecraft, and Valve formats are not supported in timeframes.
