 ### DEM Advanced settings
 
-- Multiplier: the height of the map is multiplied by this value. So the DEM map is just a 16-bit grayscale image, which means that the maximum available value there is 65535, while the actual difference between the deepest and the highest point on Earth is about 20 km. Just note that this setting mostly does not matter, because you can always adjust it in the Giants Editor, learn more about the DEM file and the heightScale parameter in [docs](docs/dem.md). By default, it's set to 1.

Just note that this setting mostly does not matter, because you can always adjust it in the Giants Editor, learn more about the DEM file and the heightScale parameter in [docs](docs/dem.md). To match the in-game heights with SRTM Data provider, the recommended value is 255 (if easy mode is disabled), but depending on the place, you will need to play with both multiplier and the height scale in Giants Editor to find the best values.
 
 - Blur radius: the radius of the Gaussian blur filter applied to the DEM map. By default, it's set to 21. This filter just makes the DEM map smoother, so the height transitions will be more natural. You can set it to 1 to disable the filter, but it will result in a Minecraft-like map.
