Does Tidal Nexus Online use AI-generated content?

Yes. The developers disclose AI-generated content on the game's Steam page:

We used generative AI tools to create base 3D meshes for some of the NPCs and initial compositions for achievement icons. These assets were not used 'as-is'; our team manually performed UV unwrapping, created custom texture masks, and modified the materials to ensure they work with our custom-made in-game shaders. This manual rework allows the assets to match our game’s unique visual style, performance standards, and lighting requirements.
