Scene units converted to

Export > File Type Specific options > Advanced options > Units >

Use this menu to specify the units to which you want to convert your exported scene. Modifying this setting directly affects the Scale Factor value applied to the exported data.

The plug-in determines the default units by looking at the Maya System Units option in the Window > Settings/Preferences > Preferences > Settings category.

In the FBX UI, the displayed Scale Factor uses the FBX Unit setting for its calculation. The plug-in determines the FBX Unit setting from the host application system units.

On export, the plug-in applies no default scaling since the export and system units match. This results in a Scale factor of 1.0.

NoteVerify the system units your Maya scene uses so that you can control whether the plug-in needs to scale your scene. This way, it exports with the units you want. Maya lets you change the System Units without affecting the scale of your scene. Changing the system unit in Maya avoids scaling on export when not required.

Example

If you export a file that is in the same Unit setting as the System Units of your Maya scene, there is a match of units and the displayed Scale Factor is 1.0. No scale conversion is applied.
