  On my phone but very interested in this (hence leaving a comment so I can find it later). What’s the variation, can we generate different maps from the same low res seed?<p>I’m interested in this because “macro maps” can be hand built in a way that may want to preserve gameplay balance while individual games can still feel broadly unique.

    Thank you! Yes as well as the input image you can pass in a seed value (otherwise the result is deterministic). I hadn&#x27;t tried it with pure noise rather than satellite data but it does pretty well: <a href="https:&#x2F;&#x2F;jgibbs.dev&#x2F;assets&#x2F;terrainsr-noise.png" rel="nofollow">https:&#x2F;&#x2F;jgibbs.dev&#x2F;assets&#x2F;terrainsr-noise.png</a>

  can you talk to some about how you trained this? this is such a neat idea!!
