Export All/Selection Options

General Options

File type: Specifies the file type to use for the scene export. The selected file type determines which export options appear in the Export Options window.

Note: As of Maya 2014, the mayaBinary (.mb) file format uses 64-bit indices. Scenes exported as .mb files are not compatible with versions of Maya earlier than 2014.
Default file extensions: When on (default), exports the file with the extension for the selected File type.

Reference Options

Specifies export options for scenes that contain file references.

Preserve references: If Preserve Reference is turned on, the references within the exported file are preserved. If it is turned off, all references are exported within the file; that is, they are no longer references, but are now objects in the scene. The default is off.
Export unloaded references: Exports any unloaded reference files associated with the current scene.
Keep only a reference (Export Selection only): Exports selected objects in your scene as a referenced file and loads them back into your current scene with the specified namespace options.
Use namespaces: Exports the reference with the namespace you specify. See Namespaces.

Prefix with

Specifies how the namespace is generated.

the file name: Specifies that the referenced file name is added to the beginning of object namespace.
this string: Specifies that a text string is added to the beginning of the object namespace.

Include Options

The following Include Options depend which export file format you select.

Include these inputs

You can enable/disable export of these specific node types by turning on or off the following:

History: This is the UI equivalent as the file -constructionHistory (-ch) command.
Note: You can export selection on connected nodes in the Node Editor. If the construction history input option (History) is off (unchecked), the selected nodes exported maintain their historical node attribute connections between one another, despite this setting. In some cases, any auxiliary node(s) that are hidden and not selected prior to the export may break those node connections. For this specific workflow, enable the display of Auxiliary nodes in the Node Editor Show menu to assure they are included in the selection prior to the export selection operation.
Channels: This is the UI equivalent as the file -channels(-chn) command.
Expressions: This is the UI equivalent as the file -expressions(-exp) command.
Constraints: This is the UI equivalent as the file -constraints(-con) command.

Include Texture Info

When on, texture images are included in the export.

Additional Export options

The following export options apply only to FBX, USD, Obj, Atom, X3D, and any other custom exporters.

File Type Specific Options

These options change depending on what you select as the File type in the General Options.

Note: For FBX Export, see FBX Export File Type Specific Options in the Maya FBX Plug-in Reference.

Note: For USD File Type Specific Options, see USD Export options.

Use full names for attributes on nodes

Lets you toggle whether to use full names.

Note:

When you export a selection, in addition to the selected nodes themselves, the following associated nodes are also exported:

parents of selected nodes
blind data template nodes
light linker nodes

Include

Connections

Include Children: When on (default), the hierarchy below the selected object(s) is included in the export.

Thumbnail/Playblast Options

These are the same options as in Save Scene Options. See Create thumbnails and playblasts for scene files for information on using these options.

Maya native file (.ma and .mb) options

For Maya ASCII (.ma) and Maya Binary formats (.mb), the Export All options are the same as the Save Scene As Options.

Note: The mayaAscii and mayaBinary file formats are the only ones that preserve all the information contained within your scene. Setting the output format for an export using the Export Options box will change your default export format for the current and subsequent export operations. If you set the output format to something other then mayaAscii or mayaBinary and export using that format and then quit without saving the entire file then you can lose data.

Always check the export type in the export file browser to ensure you are writing the file using the expected file format.

Move file options

Attributes

Type the name of an attribute in the Attributes box and click Add to add the attribute to the list of attributes to use when importing or exporting. If the attribute is already included in the list, a duplicate is not made. To remove an attribute, type the name of the attribute and click Remove. You can add several attributes at one time by separating them with a space.

From Channel Box

Click From Channel Box to combine all of the selected objects in Maya, in the order of their selection, with the channels selected in the Channel Box and place them in the list. For example, if sphere and cone are selected, and tx, sx are selected in the Channel Box, sphere.tx, sphere.sx, cone.tx, and cone.sx are added to the list of attribute to import and export.

Remove Selected

Click Remove Selected to remove all of the attributes selected in the list.

Remove All

Click Remove All to remove all of the attributes from the list.

Precision

This is ignored in file export. For file import, this sets the precision of the file.

When you click import or export, the move file is written or read and only the attributes in the list are affected.

Animation curve options (animExport file type)

You must have the animImportExport plug-in loaded to be able to select the animExport file type and see these options. (See Load or unload Maya plug-ins.)

Precision: Sets the precision of the numbers stored in the file. The choices are:

Float: Eight digits of precision
Double: Seventeen digits of precision
Custom: A setting between 1 and 18.

File Contents: File contents settings:

Use node and leaf attribute names

When turned on, the node and leaf attribute names in the clipboard are written to the file.

When turned off, only the full attribute name is written to the file.

Verbose units

When the Verbose units check box is selected, long unit names are used in the file, otherwise short unit names are used.

Hierarchy: The Hierarchy setting provides control over which nodes are copied within a hierarchy.

Selected: Only the selected object’s animation copies to the keys clipboard.
Below: Copies the animation of the selected object and all objects below it to the clipboard.

Channels: This setting is available when you want to copy only attributes selected in the Channel Box.

All Keyable: All keyable channels of the selected object’s animation are copied to the clipboard.
From Channel Box: Only those channels selected in the Channel Box are copied to the clipboard.

Control Points

This option enables or disables the copy action for all the CVs, polygon vertices, and lattice points associated with a geometry shape (or transform node hierarchically above the geometry shape).

Normally, when a control point is copied, only the selected control point is copied. The Control Points option enables the copying for all the control points associated with an object. This is useful when you are doing control point-intensive animation and don’t want to select each control point to copy the animation.

Shapes

Sets whether the animation of a shape attribute of an object as well as the animation of the associated transform attribute are copied, or if only the transform node’s animation is copied.

Generally, when an object is selected in a modeling window, the transform node (above the shape hierarchically) is selected.

For example, if a camera, NURBS object, or light is selected, the associated transform node is selected for copying.

Time Range

Select from the following options to specify the segment of animation to export from the selected object(s):

All: Copies all the animation information of the selected object or objects to the keys clipboard.
Start/End: Copies only the animation information in the range specified in the Start Time and End Time fields of the selected object or objects to the keys clipboard.

Help Images: When checked, this option displays a diagram of the copy action, and in particular represents graphically the two methods of copying animation information.
Method: Select from the following options:

Keys: Copies only keys within the selected range to the keys clipboard.
Segments: Copies animation curve segments and any keys in the selected range to the keys clipboard.

Note:
The Segments method of copying keys creates keys for the copied animation segment at the start and end times in order to preserve the shape of the animation curve, if keys do not already exist at those points.
