Hello there!

I'd be happy to give you an overview of mesh terrain scenery, along with an explanation of Digital Elevation Models (DEM) and how they're used in flight simulators.

Mesh Terrain Scenery is a type of addon for flight simulators that enhances the representation of the earth's surface. It achieves this by adding greater detail and accuracy to the elevation data, which in turn results in a more realistic depiction of the landscape.

In order to better understand how mesh terrain works, let's break down a few key terms:

Digital Elevation Model (DEM): This is a digital representation of the earth's surface, which uses a grid of elevation data points to create a 3D model. DEMs are derived from various sources, such as satellite imagery, aerial photography, and ground surveys.

Mesh: In the context of flight simulation, a mesh refers to the network of interconnected triangles (or polygons) that form the 3D model of the earth's surface. This is generated based on the DEM data and serves as the foundation for terrain rendering in the simulator.

Now, when it comes to using mesh terrain scenery, the process generally involves the following steps:

  1. Obtain a mesh terrain addon for your flight simulator of choice. There are numerous sources for mesh addons, but one reliable option is Fly Away Simulation, which offers a wide selection of terrain enhancements for various simulators.
  2. Install the addon according to the specific instructions provided by the developer. This typically involves placing the addon files in the appropriate folder within your flight simulator's directory.
  3. Enable the addon within your flight simulator's settings. Depending on the simulator, this might require adjusting the scenery library, activating the addon, or modifying the scenery.cfg file.
  4. Adjust your simulator's terrain settings, if necessary. Some addons may require you to tweak settings like mesh resolution, texture resolution, or terrain detail to achieve the best visual results.

Once the addon is installed and enabled, you should notice a significant improvement in the accuracy and detail of the terrain in your flight simulator.

Keep in mind that mesh terrain addons can sometimes be resource-intensive, so it's important to find a balance between visual quality and performance that works best for your system.

I hope this helps you understand what mesh terrain scenery is and how it can be used to enhance your flight simulation experience. If you have any other questions, please don't hesitate to ask!

Happy flying!
