For 2011 game Total War: Shogun 2 I've created all battle map vegetation models (trees, shrubs, grass), most of ground textures, enviroment settings, graound sculpting and battlemap editing (terrain tiles blendmaps painting, populating map with trees and other objects).
There were 4 seasonal variants for all vegetation and environment settings.
