This scenery is directly distributed with the v16.6601 of Outerra. You can access it inside earth2 (30/76 SRTM), with the cam_pos "Monterrey - Airport 1".
The location was discovered by Cameni, it's a really good example of the quality and detail the new dataset add to the engine. Monterrey is located in Mexico, the city was too large to be done by hand but this scenery is not entirely fictional, some elements are using real locations.
Warning /!\ If you installed the new version over an existing build, the installer uncheck "Test areas" by default and the scenery won't be installed. You can download an alternate .otx here if you want to test the area anyway:This post will mostly be a little guide of the area, there are several little things to see.
This airport is the start location, in the exact location of the real city. Two runways, it's a simple start point near the nice young mountains of the surroundings.
Really close, to the west of the airport, you will find this small village (25.712318, -100.539891). Two dirt roads are going from this village to the two next locations, and I really recommend to jump into a Truck to visit those, especially the Vulture Nest temple.
This test track was tested with the Tartra. If you can't reach the end, you should feel ashamed.
The Vulture Nest temple is the other location near the airport. I spent a lot of time testing the track to acess it, so set the weather to dynamic, jump into the truck in the small village, and enjoy the ride
This airport is the "real" Monterrey airport. You can follow the freeway next to the fictional airport to find this location
