I am a beginner in the use of blender and in this community, so I do not know if this is the appropriate place to make these comments. I'm trying to make blender the landscape that is shown on the next page Landscape construction, since I think blender can do it in a faster way, but I still do not know how to do it, if someone knows how to do it would be a great help, on the page mentioned above, show each step of the construction of the landscape in detail. Any help is welcome. Thanks in advance
