I hope to make a 3D model of existing landscapes in blender, with the hope of eventually adding them to video games that allow you to create your own maps. I tried using the following two tutorials with no luck: https://youtu.be/BXDSfrzR0zI and https://www.beamng.com/threads/tutorial-level-building-with-lidar.39370/
With the video, I do have 3D maps, but I think I have too large an area with too low of a resolution. This is because when I try to zoom in, it seems the roads are a bit blurry. I am trying to start out with somewhat large areas, like the island of Nusa Tenggara Timur in Indonesia, with the hopes of slicing out a smaller section that can be used in a game without crashing. I am quite new to blender and while I can follow along the video tutorial, I’m not 100% understanding everything I’m doing and what the alternatives are.
