As we are modeling the real world we do not have space to model everything. We need to develop “scenes” that we decide to use. Two adjacent scenes may not have much in common, therefore, to reduce the jarring effect of this change a “scene divider” is used. The road bridge pictured below can be an effective divider. I especially like this road as it looks very realistic. It is very well worn, with missing divider paint and cracks in its surface.
