This node exports a terrain as an image file. The resulting image is gray scale.
To add an Export Terrain node, right-click in the Graph Editor and select Create Node > Export > Export Terrain.
Double click on the node to open its parameters:
To export a terrain:
File names with Unicode characters are supported.
If you have already saved your project, type just a file name to export it to the same directory or a sub-directory of your project. This is useful, for example, if you have a second project in the same directory and want to import into it the exported file from the first project. There is no need to type the file directory, just the file name or the sub-directory and file name.

For 32-bit formats, the heights are saved directly as they are. In this case, there are no values between 0 and 1.
Minimum and maximum terrain values are not
saved in the image file.
The range is not available when exporting to a 32-bit image file, because in this case, the terrain is exported using the real heights and not values between 0 and 255 (for 8 bits) or between 0 and 65535 (for 16 bits).
The export is confirmed by a pop-up dialog:
The Tiff (8-bit, 16-bit, or 32-bit) and Asc formats are used to store geographic information, such as the longitude and latitude coordinates of the terrain. If the terrain was imported from a file in the same Tiff format or Asc, which contains geographic information, this information is read and kept by Instant Terra, and then written during the export.
If the terrain size has been modified (for example, with a Crop node), the geographic information may no longer be valid.
