UPDATE 2023-09-01: Added Blue Gem Mini!

UPDATE 2023-07-03: Added flat color options for water and land!

UPDATE 2023-06-18: Realistic topography/bathymetry height meshes added!

Blue Gem Earth is designed to help tell better stories about the world in geography-oriented games, YouTube videos and editorial presentations. Built with artistically crafted color maps that are draped over Nanite-powered terrain data, it’s designed with raytracing, to run in real-time. Blue Gem offers visually striking, vertically exaggerated (~11x) or realistic topography and bathymetry heights (2 different levels), adding depth and dynamism to the appearance of the land and ocean floors, as the shadows cast over the surfaces. Additionally, it harnesses Epic’s atmospheric lighting system, allowing dynamic lighting and shading adjustments based on the sun angle, turning the city lights on and off depending on the light visibility.

If you like it, please leave a review! It motivates us to improve the project. If you have suggestions for improvements please ask a question or let us know. Thank you!

Surface

The color map consists 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 the production.

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

[/Script/WindowsTargetPlatform.WindowsTargetSettings]

DefaultGraphicsRHI=DefaultGraphicsRHI_DX12

Disclaimer:

The translucent water meshes in this project are not Nanite enabled by default (this is intended). Enabling Nanite on the water meshes will stop them from being translucent.
