Giga Earth
Showcase Video
Giga Earth is derived from over 2 billion polygons, with the optimised terrain data powered by Nanite, enabling cinematic viewing of Earth for games, cinematics and interactives, in real-time. This Earth is built to scale and leverages Epic's atmosphere to dynamically light and shade the atmosphere depending on the angle it's set to.
Surface
The color map comprises 81,920 pixels wide and 40,960 pixels high and has been hand painted to have many data processing artefacts removed. The normal map comprises 81,920 pixels wide and 40,960 pixels, and allows for normal flatness to be adjusted, changing the intensity of the terrain features to better suit the different artistic needs of near and far shots.

Hardware
Nanite on PC requires the following;
- NVIDIA: Maxwell-generation cards or newer
- AMD: GCN-generation cards or newer
Notes:
This project is ~7 GB in size.
This project requires the 'Volumetrics' plugin be activated to use the volumetric clouds.
Volumetric clouds have limited range of shadows (~400km) - see gallery for examples. Volumetric clouds will cause shadow streaking beyond this if viewed from far out distances.
Giga Earth requires SM6 to be enabled for Nanite if using Unreal Engine 5.1+. SM6 is enabled by default in Unreal Engine 5.1+.
- This project does not include heightmaps.
- Please press play and then stop in the editor to execute the recommended console variables.

If large seems are still present, navigate to your Unreal Engine Project Folder, and locate DefaultEngine.ini. In a text editor, such as Notepad or Notepad ++, edit this file. Change the following
from
[/Script/WindowsTargetPlatform.WindowsTargetSettings]
DefaultGraphicsRHI=DefaultGraphicsRHI_Default
to
