A little line of code called: Temperate, EI_TROOPER.ALO, Urban, EI_TROOPER.ALO, Arctic, EI_TROOPER_Snow.ALO, Volcanic, EI_TROOPER_Sand.ALO, Desert, EI_TROOPER_Sand.ALO, Forest, EI_TROOPER.ALO, Swamp, EI_TROOPER.ALO Neat, huh? With this, you can do pretty much anything to make units change based on environment. This can work for simply changing textures as well.
