Writes a file containing the open document's mesh data in the specified format. Current export formats behave as follows:

Obj: Vertex positions will be exported with v lines. The first Texture Coordinate attribute with at least 2 components, if any, will be exported with vt lines. The first Normal attribute with at least 3 components, if any, will be exported with vn lines. No other attributes are included in exported obj data.

glTF (text or binary): [!todo]Currently, all glTF exports will include the following attributes:
[list-]
[*]POSITION, set to vertex's primary position.
[*]TEXCOORD_0, set to the first Texture Coordinate attribute found, or default values of [nobr]{0, 0}[/nobr] if not present.
[*]NORMAL, set to the first Normal attribute found, or default values [nobr]{0, 0, 1}[/nobr] if not present.
[*]COLOR_0, set to the first Color attribute found, or default values [nobr]{1, 1, 1, 1}[/nobr] if not present.
[/list-]

If an armature is present and the "Include bones" checkbox was selected at export time, the following attributes will also be included:
[list-]
[*]JOINTS_0, set to the first Bone Index attribute found, or default values of [nobr]{0, 0, ...}[/nobr] if not present.
[*]WEIGHTS_0, set to the first Bone Index attribute found, or default values of [nobr]{1, 0, 0, ...}[/nobr] if not present.
[/list-]

Stem3D MeshData: [!todo]Currently, exported vertex format behavior is equivalent to glTF.

Additional formats, options, and possibly custom exporters may be added in the future.

The export dialog may contain some additional options, depending on document contents and export format:
[list-]
[*]Include hidden items: If checked, all mesh geometry in the document including hidden faces will be exported. If unchecked, hidden faces are omitted from exported data. Available only if some faces are hidden.
[*]Ignore mirror: If checked, only one half of mirrored geometry will be exported. If unchecked, mirrored geometry will be symmetrically copied on export, in the same way it appears when rendered. Available only if [link=mirror_mode]mirror mode[/link] is active.
[*]Include bones: If checked, the mesh's armature will be exported alongside its geometry. If unchecked, the armature will be omitted from exported data. Available only if the mesh has an armature, and the selected export format supports armatures.
[*]Apply pose: If checked, the currently displayed pose will be baked into to exported geometry. Available only if the mesh has an armature with a pose currently being displayed.
[*]Embed vertex data: When checked, vertex data will be directly embedded as Base64 data rather than being stored in a separate binary file. Less space-efficient than binary export, but allows full data to be contained in a single file. Available only for non-binary glTF exports.
[*]Texture options:[list]
	[*]Don't export: All textures will be removed from exported mesh data.
	[*]Reference only: Exported mesh files will be written to reference texture image files, but the images themselves will not be exported.
	[*]Separate file(s): Each texture will be written as a separate image file alongside exported mesh data.
	[*]Embed (binary): All texture images will be embedded in a single binary file exported alongside mesh data. (glTF only)
	[*]Embed (JSON): All texture images will be embedded as Base64 in the JSON file containing mesh data. (Non-binary glTF only)
