AI Generated Content Disclosure
The developer filed this on the Steam store page. It is not a guess by active.games.
Terrain textures, elevations and biomes in game are ML generated. Most of the work on the terrain also uses machine learning techniques both offline (pre rendered) and at runtime. We train our own models with our own sourced data, and it is rigorously vetted for legal concerns.
