I’ve been working on a small tool for drawing 2D tilesets. The original goal was to generate tiles for texture synthesis experiments so we can use the drawn tileset, reconfigure it to make a larger image that is also seamless.
As I built it, I ended up following a lot of the classic 2D game tileset adjacency logic with a tileset template. It may be useful for anyone who want to draw tilesets for games too.
