# MS3D Export Options

The MS3D Export Options window is displayed when you save a model in MS3D format. It allows you to specify how you want bone joint influences to be saved.

The Vertex Format options specify which MS3D vertex subversion you want to save as. If no vertices in your model are assigned to more than one bone joint, select Subversion 0. Otherwise, select Subversion 1, 2, or 3.

- Subversion 0 - Original file format, a vertex can only be assigned to one bone joint.
- Subversion 1 - A vertex may be assigned to multiple bone joints, the weight range is 0 to 255. Models in this format do not render correctly in MilkShape 3D 1.8.0 and later.
- Subversion 2 and 3 - A vertex may be assigned to multiple bone joints, the weight range is 0 to 100.

The Subversion Options section includes options that only apply to specific subversions. The Vertex Extra option is a 32-bit number that is saved with the vertex data in Subversion 2 and 3. The Vertex Extra 2 option is a 32-bit number that is saved with the vertex data in Subversion 3. The numbers are specified in hexadecimal. The numbers supplied is used for all vertices. There is no way to set these values for individual vertices.

Click Ok to save the model with the specified options or click Cancel to ignore any changes.
