Mesh Geometry
• When exporting mesh geometry, you can
export triangles, polygons, or quadrilaterals.
• Normals are exported by default.
Groups
• If you choose to group by object, then the
exported information will be organized by
object. This information will be available when
you import the file so that you can choose
certain objects to impor t rather than the entire
file.
• If you select to group by material, then the
exported information will be organized by
materials. When importing, you can select to
only important elements that are associated
with a particular material.

Group and M aterial group
Group by—Lets you group the information in the
OBJfilebyobject,material,orbyusingdefaults.
The choice you make will be important when you
want to import the file. For example, it may be
useful to group by m aterial if you have several
objectsthatusethesamematerial.
Use materials—Deter mines w hether the materials
that are associated with the object are also
exported to the OBJ file.
Create materi al libr ar y—Determines whether a
separate library is created to store the information
about the materials. This creates a MTL library in
thesamedirectoryastheOBJfile,firstprompting
for information with the MTL Export dialog (page
3–590).
