RPGMapEditor

RPG Map Editor is a browser based software application designed for creating tactical battle maps for Dungeons and Dragons and other tabletop roleplaying games. The tool functions as a software as a service platform that allows users to build encounter spaces using WebGL technology directly within a web browser. Its primary purpose is to provide Dungeon Masters with a streamlined environment for generating visual aids that can be used for digital play or printed for physical tabletop sessions.

The application includes a variety of features such as terrain painting brushes, a library of stamps and props, and a customizable tactical grid. Users can manipulate environmental elements to create specific settings including forests, taverns, and dungeons. The editor supports saved map files and provides a PNG export function specifically formatted for integration with virtual tabletop platforms like Roll20 and Foundry. Technical features include ambient lighting controls and a scene preview mode, with a fallback to still images for browsers that do not support WebGL.

The typical workflow involves painting terrain strokes to define the environment, placing readable objects to establish cover and chokepoints, and aligning the tactical grid to ensure scale accuracy. Once a map is completed, the user exports the file as a PNG image to be imported into a virtual tabletop. The software is designed for efficiency, with estimated build times ranging from ten to thirty five minutes depending on the complexity of the encounter. This process is intended to replace hand drawn grids or complex image editing software with a specialized toolset for rapid map preparation.
