File Output

The File Output device saves a heightfield or grey scale mask to disk.

Please note that only the heightfield information is saved — any coloration created in World Machine needs to be saved separately, using a Bitmap Output.

Device Parameters

Set This button brings up a dialog to specify the filename to save to disk.
Use absolute path for setting filename If checked, the filename will include the full path. Otherwise, it will contain the relative path if possible.
Participate when building tiled worlds When checked, this output will export tiles during a tiled build.
Save file every build If this is checked, every time you build the world (press the Green build button), the File Output device will save the heightfield to disk.
Write output to disk Writes the current build results to the specified file. If the world is not built (the File Output’s status indicator is red) you will be prompted to build the world
