I constructed these by "out painting" tiles one by one with some overlap. Turns out Nano Banana Pro is great for simple inpainting tasks as well. It handles strict instruction following surprisingly alright, there are occasional stitch problems but so far so good. I tried a bunch of interesting, historical art styles too, from Parisian Lithographs (Toulouse-Lautrec style) to Soviet Constructivism and WPA National Park posters etc. Pretty capable at replicating the art style without any reference image too. The only issue is that the generation colors fade for some reason as the tiles get further away. Since this would be extremely time consuming to do manually I decided to vibe code a tool just for this. It's a web app that allows you to generate endless, seamless isometric worlds and download the stitched image and individual tiles as well. It took a while to build it but google ai studio and gemini 3 pro are pretty capable too lol.
Let me know what you think!
