When you select Model Default from the preset drop-down menu 
, the Game Exporter displays the following standard set of options for exporting models.
For information on creating your own preset with additional or different FBX options, see Create a Game Exporter preset. For information on the FBX options, refer to the FBX Reference, available online, or from the Maya Help.
Geometry
- Smoothing Groups
-
Converts edge hardness/softness to Smoothing Groups for the exported geometry. When off, only explicit normals are exported with the file.
- Smooth Mesh
- Turning this on bakes the in-viewport subdivision of the polygon mesh into the exported geometry.
- Split-Vertex Normals
- Splits geometry vertex normals based on edge continuity. Vertex normals determine the visual smoothing between polygon faces.
- Triangulate
- Automatically converts polygons into triangles for the exported geometry.
- Tangents & Binormals
- Creates tangents and binormals data from UV and Normal information on exported geometry. This way you have an accurate tangent space representation of your geometry that you can use in some game engines.
- Skinning
- Sets whether to export all skin deformation information for skinned meshes.
- Blendshapes
- Sets whether to export any blend shapes on the exported object(s).
Miscellaneous
These options let you set whether to include Animation, Lights, and Cameras in the exported file, or only the target mesh.
