Make your terrain as big as you want, you can create a terrain in MED, or use a model. Then apply a terrain mutitexture shader, such as the one included with A6 and A7 in the mtlfx file, follow the directions and it will work perfectly.
Both types of terrrains will be effected by sunlight and shadows.
