Ok. Lets see it :)
1. Use MaxSuperficial Tool
2. Create the map. My LOD4 square is 160km×160km and use 256*256 BMP from Google. LOD3,2,1 square is 80km×80km with 512×512 BMP and the LOD0 sqaure is 40km×40km with 1024*1024 BMP
The red marked Area of map is my high meshed project's area.
Its area 800km*600km with 100m SRTM mesh (optimized).
- The Mission Editor Geophysics Map's texture is Land_Map, Land <- Red marked toolbar area
- Add LOD value (green marked area)
- Export the land_map_L0.sup and Export the land_map_L2.sup files (yellow marked area)
Use the blue marked area if you create land.lsa2 mesh model file.
