Landscape Creation#

  • terrain.party gives a square height map of 60x60 to 8x8 km2

  • tangrams gives a heightmap that fills your screen

../../_images/height_map.png

Note

terrain.party often timeout

Tangrams#

  1. Download a height map that fills your browser screen, save the heightmap range range=(lowest - heighest)

  2. If your heightmap is big, split it into multiple quadrants, the names must follow the convention <name>_x0_y0 with 0 x 0 is the center of your image.

  3. Exports your heightmap as 16bit gray scale (PNG or RAW)

  4. Create a new level

  5. Enable landscape mode

  6. Import from file

  7. Compute the z-Scale

# increase the range if you want to account for sea level
range (cm) = range (m) * 100
z_scale = range (cm) * 0.001953125        # (0.001953125=1/512)

Note

To get a square heightmap you may use your browser developer tools to mock the desired screen size

Note

One pixel of your height map is equal to 1 meter in Unreal Engine

Note

The URL contains the lat/long of the pixel at the center. Using your browser developer tools you can query the size in meters scene.view.size.meters

scene.view.size.meters
Object { x: 5243.083422156026, y: 5243.083422156026 }
