What is a heightmap file?
In computer graphics, a heightmap or heightfield is a raster image used mainly as Discrete Global Grid in secondary elevation modeling. Each pixel stores values, such as surface elevation data, for display in 3D computer graphics.
What is height map in Unreal?
A heightmap is a grayscale texture that stores landscape height information. Black color is low elevations or valleys and white color are high elevations or peaks. All landscapes in UE4 rely on heightmap data to create the terrain.
Where can I find Heightmaps?
Koordinates and Landcare Research are two sources for heightmaps. They have maps of all of New Zealand in GeoTIFF and ASCII formats, which can be opened with QGIS. These websites know heightmaps as Data Elevation Models (DEMs).
What does a height map look like?
A heightmap should be a greyscale image, with white areas representing the high areas of your texture and black representing the low areas.
Can you make a height map from a picture?
With this a good coder/mathematician/mapmaker could (maybe) calculate the (close approximate) vertical relief and translate that into a greyscale image usable as a heightmap. But from the pic alone, it’d not be feasible except by trial & error. George, sorry to disappoint you, but your picture is NOT a height map.
Why does an image not work as a heightmap?
Guys, his image won’t work as a heightmap or displacement map because the greyscale tones do not correspond to height values – they are shadows and highlights caused by the relief. The dark shadows would become deep pits and the bright highlights tall peaks, none of which would actually match the real terrain.
How does the size of a heightmap affect unity?

How to create a mesh from a height map?
I know there are a lot of tutorials out there that tell you how to create a mesh from a height map. E.g. to create some terrain. I wish to know how I can do the reverse. So I have a mesh with a surface going from 0 to 10mm in height for example, and map the 0-10mm range to a grayscale 8bit grayscale bitmap (so 0 to 256).
