I haven’t had much time lately for RTS4, but I needed a break from Uni work, so decided to build a quick farm optimising website. Drag around to pan the camera, click items on the right to select that type, and click in the world to place them. Select objects and drag them to move them, or press delete to delete them. The average distance is calculated as the average distance from 4 points on each farm to the nearest drop site.
Update: Added collisions and shadows, it looks a lot nicer now
