The tricky part was the tulips. I modeled the tulips using manual LOD’s but ended up distributing only the lowest level of detail and I decided to use hardware instancing which we implemented by switching to Ogre 1.8. I distributed the using this mel 3D paint script which I suggest checking out if you ever need to paint geometry.
I modeled the Pool of Reflections myself and exported/implemented it into the game. First we had to cheat since the terrain is not entirely accurate in this area. So I built the pools onto an artificial hill. This is not historically accurate, but it looks good and we can keep the fair more or less planar which makes it easier to put together on so may levels.
