This is regarding the theLevelInfo element in the World Editor. I would like to request the ability to specify "elevation above sea level" as a Z-coordinate value within the map. The specified value should be reflected as the altitude. As you know, from a physics perspective, vehicle behavior changes as altitude increases. For example, at 1000m higher elevation, the temperature is lower, etc. Additionally, in reality, there are roads and areas that exist below sea level. For instance, in Japan, the Shuto Expressway has tunnels that are located below sea level. Currently, someone is developing a Shuto Expressway map mod, but due to the presence of an invisible ground layer at Z-coordinate 0.00, it is impossible to create roads below 0.00. As a result, they have set the baseline Z-coordinate to approximately 850m. If this feature is implemented, we could set theLevelInfo as follows: ▼Map Elevation above sea level: [850m] This would help minimize the impact of altitude-related physics effects.
