Following the update to NZAA after the NZ World Update, NZWN Wellington Airport has now also been updated to fix some of the big issues caused by World Update 12. The biggest issue encountered was the new NZ TIN and Terrain mesh applied by WU12, which creeped into the NZWN surrounding and caused some jarring lines along the coast. This essentially broke our hand painted watermask and caused the water color to change drastically.
The TIN exclusion was re-balanced, allowing some areas to show photogrammetry, and some of the weaker TIN areas to be excluded, showing sim-generated homes/buildings instead.
The more complex fixes were related to the custom terrain, which quite literally had to be re-done. The NZ mesh supplied by the WU12 update caused some significant terrain issues, which made the runway bumping and uneven. A lot of work was involved to re-do our custom terrain which accurately depicts the slope of the runway, from north to south. Significant work was also done at the south end of the runway, where the road tunnel going under runway 34 was essentially re-done. Note that some rough spots may be seen, this will be improved as future patches arrive.
Lastly we've implemented a custom ILS solution, so the scenery no longer relies on default sim data. This should help with many advanced addon aircraft which are either already out, or coming soon.
The update is now available through Contrail if you purchased NZWN through the Flightbeam webstore, Contrail or Simmarket.
For MSFS Marketplace customers, expect the update to arrive around the end of this month.
