Unreal

The easiest way to import a Gaea terrain into Unreal Engine is to use the Gaea2Unreal plugin.

If you wish to import it by yourself, use Unreal Node to prepare the output to fit your terrain size as required by Unreal Engine. Then you can manually import the terrain.

1. Enter Landscape mode.

2. Click Import from File.

3. Click the button next to Heightmap File and select your heightmap.

4. Calculate the Z scale for your heightmap using the formula (Max height of your heightmap in meters) x (100 to convert to centimeters) x 0.001953125.

5. Click Import.

If the Z-scale calculation feels too complex or you are not getting accurate results, use the Gaea2Unreal plugin to import your terrain. Gaea will prepare these calculations and other factors for you.

You can follow the exact instructions on Unreal's official documentation:
