Blue Gem Earth

Showcase Video

Blue Gem is derived from over 2 billion polygons, with the optimised terrain data powered by Nanite, enabling stylized viewing of Earth for games, cinematics and interactives, in real-time. This stylized Earth is built with a vertically exaggerated topography and bathymetry and leverages Epic's atmosphere to dynamically light and shade the atmosphere depending on the angle that the sun is set to. Raytracing is used to help bring greater realism to this stylistic rendition of our home planet.

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.
