I’ve not heard anything about training the AI, but last Q&A about a scenery gateway system (to be called “MSFS Scenery Hub”) will be implemented:
Clarification on Scenery Getway system:
Martial – We call MSFS Scenery Hub. This tool is web based, everybody can register and contribute by going to the website and download a Dev mode project. In the dev mode, you can enter the edition mode. What we did so far is mostly dedicated to data. For the moment, we are not talking about putting custom meshes there, but it will help us to improve all data there (Better placement for all buildings and improvement airports for instance). You can then upload your edition to the Scenery Hub to be validated and implemented within an update.
