Grid Cartographer is an intuitive map creation tool. Use it to quickly craft table-top dungeon encounters, block-out computer game environments, or as the perfect companion for classic role-playing games.
Users can choose from square, hexagon, and tile-map grid types to suit their needs. The tool offers a wide range of selection and editing tools, including undo/redo, cut/copy/paste, marquee, paint, and wand selections. Users can also add text labels and quick notes to the maps.
The map creation area has unlimited floor space, which users can organize into named floors and multiple tabbed "regions". This allows for the creation of large, complex maps without being constrained by page or screen size. The flexible grid setup supports limited areas as well as infinite planes.
The software includes a 3D view mode that allows users to visualize the maps from a first-person perspective. It also provides an avatar cursor to help track the player's movements as they explore the map. Some reviews mention features like interactive wall levers and treasure chests to further enhance the exploratory experience.
Users can import maps and room notes from the donjon dungeon generator. Maps can be exported to various image formats like PNG, BMP, and TGA, with options to create "player maps" through filtering. It also supports exporting maps to 3D mesh formats like OBJ, as well as JSON/XML data for use in game engines like Unity, Godot, and Unreal.
The software includes a scripting system that allows users to export maps to proprietary data formats. Reviews mention the ability to write scripts in the Squirrel language to automate various map-related tasks, including creating custom GUIs and interacting with game memory.
