“Two track, eight metre high embankment, 8 metre repeat. This can be used for any height from 0 to 8 metres although part of the embankment sides buried in the ground tend to cause 'sawtooth' effect from most angles at a distance. At greater heights raised terrain can be used but its best along the grid rather than diagonally. The banks texture is slighty transparent to allow some apparent variation in texture. I tend to raise the ground and plant rocks/shrubs to stick through the embankment sides to give variety.”
