Another attempt at Blender landscapes using the Ordnance Survey Terrain50 DTM and Meridian2 datasets.
The Meridian2 features are draped over the DTM which is vertically exaggerated by 150%.
Water features and a sea layer are used to create an image texture. This is used in a UVmap to create the glossy looking sea and rivers in the final render.
Some work needs to be done on the image texture resolution and some smoothing of the DTM needs to happen to get rid of the contouring effect. But I still like them.
