AI is here... At last!

From Build 95, you will now be able to view the very basic AI train system.

This is a huge step for the game as this is one of the final core features which was on my mind and couldn't figure out how to get it to work.

Currently there is no spawning system, but instead the AI have to be manually placed into the world manually in UE4. This will be a simple implementation once I have figured out a performant way of doing it.

I have also made numerous LODs for all the common assets found in the world, reducing wasted performance rendering high poly meshes, while only increasing the project size marginally. I think this goes hand-in-hand with the increased requirements of having multiple trains running around together.

For the time being, I have also removed many of the London Underground copyrighted material until an agreement is made with TfL in the future.
