I'm GMing a Lancer TTRPG one-shot for a group of friends soon, and for a one-shot I wanted to do my own maps instead of just the first encounter of one of the (apparently-good!) official campaigns. However, finding a hex battlemap editor proved... challenging. Short story long, I now have a script that will take in a json/yaml with tile metadata and generate a boring-but-functional battlemap. (Sample: planned "firing range" map to ensure folks are comfortable with movement, combat, etc.)
