Description
Be sure to end the specified filename with .DBO so that the file can be loaded in again correctly. It is worth noting that before saving, the vertex data is restored to the last god copy before animation changed the data, so that the model can be saved out correctly. Unless you used the special mode 2 for the "lock vertexdata for limb" command, any changes with this command will not appear.
