Giga Mars

Showcase video


Giga Mars is derived from over 1 billion polygons, with this terrain data powered by Nanite, enabling cinematic viewing of Mars for a variety of purposes, in real-time. The total color map is over 81,000 pixels wide and 40,000 pixels high which is based on real data that has then been artistically treated. The normal map is over 40,000 x 20,000 pixels, and allows for normal flatness to be adjusted, changing the intensity of the normal map features.


This project provides Mars at two different scales in two separate levels, one small stylized and artistic, while the other is built to scale.


Giga Mars requires SM6 to be enabled for Nanite if using Unreal Engine 5.1. SM6 is enabled by default in Unreal Engine 5.1.
