That sounds like a very interesting and detailed Autodrive course you are planning to create in the "Welcome To Lehndorf" map for FS25!
Mapping the road network as primary routes and field accesses as secondary routes with field boundaries will surely enhance the navigation system for Autodrive. It's great that you are considering leaving the farms and production areas for personal customization, giving players the freedom to design their own layouts according to their preferences.
Ensuring that all farms and production areas have at least one navigable point will provide players with convenient access points to various activities in the game. This approach will make the gameplay more engaging and seamless, allowing players to efficiently manage their farm operations.
The required mods, Autodrive and Welcome To Lehndorf, are essential for creating this customized Autodrive course. Autodrive will enable automated vehicle navigation, while Welcome To Lehndorf will provide the base map for building your course. With these mods, you can create a dynamic and immersive farming experience for players in FS25.
If you encounter any challenges or need assistance with creating the course, feel free to ask for help or share updates on your progress. Good luck with your project, and I hope it turns out to be a fantastic addition to the FS25 community!
