I wrote that I made Rera like North European scenery in a former post. However, it’s lacking in accuracy. The North Europe is generally Denmark, Sweden, Norway, Finland, Iceland. Lithuania, Latvia, Estonia, Germany, Poland, Russian Baltic Sea coastal place are added in a wide sense more.
I cannot be able to reproduce the all topography in one SIM. I intend to make a lake and a fjord a characteristic of Rera.
There is the firm topography called Baltic Shield in Sweden, Finland from the Norwegian southern part. It’s the very stable topography formed by Precambrian age. It planarized it by longtime erosion. And it became the topography with many lakes by wind and rain and erosion by the glacier.
Furthermore, there are many huge collision craters in this area. Those most became the huge lakes. This area is continental crust that basement rocks cropped out in depth on the surface of the earth.
Therefore, I must change textures of the ground of Rera fundamentally. A texture of the rock is used for the low place that is near to the surface of the water. And green texture is used for the position that is higher than it. Furthermore, texture of the rock is used for the position that is higher than it again.
On the other hand, Scandinavia Mountains with many fjords contact with the northwest side of the Barthes shield. During the ice age, the North Europe area was covered in the thick glacier. The glaciers have begun to retreat from the time before 12,000 years. In this case the texturw of the rock is important. A hard part was left by the erosion of the glacier.
It must be increased texture of the rock in Rera first.
