     You can export graphics from Maya in the FBX format. The necessary plugin is
     usually enabled by default, but you can check that in the plugin manager.
 
+    Maya exports the transformation as given by the scene. To include frozen

+    We recommend using default pivot points in your designs to avoid problems
+    when importing to \QDS. If you want to use a non-default position for a
+    pivot point, you have to adjust it in Maya before exporting your assets.
+
+    To export certain elements of your design, such as geometry, animations,
+    and textures, you need to adjust the settings for FBX exports under
+    \uicontrol {File Type Specific Options} in Maya export options. The
+    optional steps should only be applied if required by the project. For
+    example, including embedded media in your export simplifies moving the
+    scene to another computer but increases the file size as well as the loading
+    time of the scene since the textures need to be extracted before they can be
+    imported to the scene. This would result in the same texture existing in
+    three locations on your computer: the original location, embedded in the
+    scene, and extracted into the asset import folder.
