The ASCII-based OBJ
format makes it possible to exchange graphical data between many
applications. Both polygons and freeform geometries such as curves
are supported with this format. You can export 3ds Max files
to this format.
To export scene geometry to an OBJ file:
- From the
choose Export. Or, to export only the current selection, choose
The Select File To Export
- Enter the file name, optionally with
the .obj file name
extension. If you don’t enter the extension, open the Save As Type
drop-down list and choose gw::OBJ-Exporter (*.OBJ).
- Click Save.
The exporter dialog opens.
- Set parameters manually, or choose the
name of the target program from the Preset drop-down list. Optionally
click Map-Export and set map-export parameters.
- Click Export.
During export, a dialog
showing progress and the names of exported objects opens. When the
export is finished, click DONE to return to 3ds Max.
- Flip YZ-axis
When on, transfers all
Y-axis values to the Z axis and vice-versa. Use this when exporting
to Poser and other programs that use Y as the vertical axis and
Z as the depth axis.
Enables export of splines and
NoteNURBS curves are
exported as splines.
- Hidden Objects
When on, hidden objects are exported.
Choose whether the mesh
faces are stored as triangles, quadrangles, or polygons.
- Texture coordinates
When on, texture coordinates
are stored with the exported file. When you import the file in another
application you will be able to use this information if it is supported.
- Smoothing groups
Determines the scaling for
the contents of the OBJ file. The default value of 1.0 means no
scaling is performed.
- Use material
Determines whether the materials
associated with the scene objects are also exported to the OBJ file.
- Create mat-library
Determines whether the exporter
creates a separate file to store information about the materials.
This creates a MTL library file in the same directory as the OBJ file.
If Use Material is on
but Create Mat-library is off, the OBJ file contains a reference
to a like-named MTL file, but the MTL file is not saved. Use this
to save time if the MTL file already exists.
- Force black ambient
Sets the Ambient component
of exported materials to black.
Sets the target operating system
of the computer on which the exported data is to be used. Technically,
this setting determines the line-end characters for the ASCII OBJ
- Relative numbers
Causes face vertex indices
in exported files to be expressed as relative (i.e., negative) numbers.
This can cause compatibility issues when importing with certain
programs. If you're unable to import an OBJ file, make sure this
option is off and export again.
The precision of the exported
vertex data, as expressed by the number of decimal places.
Removes duplicate elements
of the indicated type or types: vertices, face normals, and texture coordinates.
- Write log to Export-folder
Saves a log file to the same
folder as the OBJ file when exporting via script.
When exporting to a specific
application, choose that application from the list. Presets comprise
all export settings, including geometry and materials.
- [edit presets]
Click to open a dialog that
lets you edit the presets. To change the map path for a preset,
edit the map-path setting manually or click the folder button at
the right end of the row and navigate to the new path.
While the Presets dialog
is open, you can choose a preset by clicking its name (the row highlights)
and then clicking OK.
Saves the exported files (OBJ
+ optional maps and material library) according to the current settings.
During the export, a
dialog shows the progress and saved files. When it’s finished, click DONE
to close the dialog.
