Group and Material group
Group by Lets you group the information in the OBJ file by object, material,
or by using defaults. The choice you make will be important when you want
to import the file. For example, it may be useful to group by material if you
have several objects that use the same material.
Use materials Determines whether the materials that are associated with the
object are also exported to the OBJ file.
