# Importing and Exporting FBX Cameras

Smoke supports the import and export of 3D data saved in the Alias® FBX 3D format. The FBX standard format provides a means for exchanging 3D data for scene compositions—such as cameras—between tools and packages developed by different manufacturers.

You can either import a camera you created and edited in Action, or import one from another 3D application. Once a camera is imported, you can edit its parameters, change its animation, and then export it back to the application it came from.

FBX support makes the import and export of 3ds Max, Alias Wavefront™, Maya®, Softimage® XSI™, and LightWave 3D® formats possible.

NoteSome parameters in Maya are not supported in FBX, such as Shear, FilmPostScale, and CamScale. Also, many parameters that are animatable in Maya and Smoke are not supported as animation curves in FBX. FBX Camera does not support depth of field.

For information on how to import an FBX format camera, see Importing the FBX Format.

Export an FMX camera from Action to FBX format, which can be used later by any other FBX-compatible application.
