Map your rooms, drop in objects and NPCs, write branching dialogue, and export batch commands your Evennia game actually runs. Free, and it never leaves your browser.
Click-and-drag map building across multiple floors, eight directions plus up and down, zone colour-coding, and a minimap once things get big.
Place items and characters right in the rooms they belong in. Save anything as a template so you're not rebuilding the same key fifty times.
Build branching NPC conversations visually. Export a real working EvMenu Python module, or plain JSON and text if you're not on Evennia.
Generates actual @dig, @tunnel, @open and @create batch commands. Not a mockup — it builds your map for real.
Flags isolated rooms, one-way exits with no way back, and broken links before you find out the hard way mid-playtest.
Blueprint, Forest Ledger, Crimson Archive, Slate & Steel, Violet Codex. Pick whichever one matches the game you're building.
Every map, dialogue tree, and object library can leave Mudbox in whatever shape you actually need it in.
