| NumTargetPIDs = INT | Specify the number of parts in the target mesh to be considered for mapping, followed by TargetPID#i definitions. |
| TargetPID#i = INT | Define as many part IDs as given in NumTargetPIDs. These parts are considered for the mapping. |
| NumSourcePIDs = INT | Define the number of parts in the source mesh to be considered for mapping, followed by SourcePID#i definitions. |
| SourcePID#i = INT | Define as many part IDs as given in NumSourcePIDs. These parts are considered for the mapping. |
Note: The above options limit the scope of the mapping procedure to defined part IDs. Other parts are ignored on both the source and target side.
