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
- click Export and you get your mesh as a 32-bit .exr file with the height info stored in the image's red channel.
Done

Godot

In Godot, with Zylann's Heightmap Plugin, you import your .exr as documented in the official docs.

Use the godot4 branch to actually use heightmaps with 32-bit precision!

Enjoy the beautiful export!
