# Creating animations for Sceneform

To implement animation in Sceneform, you need models with animation data. These
models are created ahead of time by artists using 3D modeling and animation
software. These animations must be exported as `*.fbx` files, then imported into
a `*.sfb` file to be used in Sceneform.

To ensure they're compatible with ARCore, `*.fbx` files should be saved using
supported settings. You can then import these files into your project as `*.sfb`
files.

## FBX asset format and requirements

We recommend and support the following settings for `*.fbx` files exported from
modeling and animation software.
