YATME
YATME is a browser-based OpenTibia map editor for Tibia 15.00+ client data.
What YATME is
YATME is a browser-based OpenTibia map editor for Tibia 15.00+ client data. It renders and edits OTBM map files using sprite data extracted from the Tibia client, with tools for tilemaps and entity placement. The project is designed for map development and administration and can be hosted alongside an OTS server. Docker Compose and Docker run instructions make the editor available at localhost port 8080 by default. Running it requires asset files from a Tibia 15.00+ client and an .otbm map; related sidecar XML files are optional. Client assets are mounted read-only while map files are read-write so edits can be saved. Sprite sheets are converted from .bmp.lzma to PNG on first startup, and the cache persists across restarts. YATME is MIT licensed, built with React 19, PixiJS 8, TypeScript, and Vite.
