The routing detailed above includes all intermediate waypoints and it is therefore appropriate to use with a simplistic FMC, such as the default FMC in X-Plane.
If you have a more sophisticated FMC, which determines any intermediate waypoints (such as the x737/UFMC for X-Plane) you may use the following simplified flight plan:
ENTC-SID->ERPUG-DIRECT->UDSAM-STAR->ENAT
