Simple Workflow Example

Blender

Create a new A.N.T. Landscape (install the A.N.T. addon if not already done so) and set
- Mesh Size to 128x128, and
- Subdivision to 129x129 (NOTE: subdivision must always be 1 higher)
  - this value is the resolution (power of 2 + 1)
While in Object Mode, open the BMesh Map-tools-tab,
- clicking on Get Status gives you feedback on your Mesh: check your resolution and copy your min and max height values,
- specify the location and filename to save to
- choose your bit-depth
  - 32-bit (best results)
  - 24-bit (good results)
  - 16-bit (potentially bad results)
- choose your endianness (default: little)
- click Export and you get your mesh as a heightmap file (.raw)
Done

Godot

In Godot, with Zylann's Heightmap Plugin, you import your .raw file like .png, .exr, etc.

Import settings

Bit depth and Raw Endianess: The ones you chose on your export
for Godot 3.x:
- only supports 16-bit raw file
Min Height + Max Height: take them from the Add-on Panel in Blender, see Min-Max.

Enjoy the beautiful export!
