| NumTargetPIDs = INT | Define the number of parts in the target mesh which are considered within the mapping. This option must be followed by TargetPID#i definitions. |
| TargetPID#i = INT | Define as many part IDs as given in NumTargetPIDs. These parts are considered for the mapping. |
Note: The options above specifically narrow down the scope of the mapping procedure to defined-part IDs. Other parts are ignored on both the source and target meshes.
