Independent developer Robe of Fire will release Miso Editor in Early Access on itch.io on 23 November 2026. It’s a Windows tool that turns one character into sprite sheets in up to 64 directions.
Miso Editor rigs the character automatically, sets up its animations, and renders the sprite frames. Robe of Fire says rigging, motion, and baking all run on the user’s own PC. The developer already uses it: the new enemies in Fire Field, its 90s-style isometric 2D action RPG in Early Access on Steam, are sprites made with the tool.
grew out of my experience developing the action RPG Fire Field.

According to the press kit, the flow runs from a picture to a 3D model, then rigging, a weapon, animation, sprites, and a preview before export. Users pick from 1 to 64 directions with camera presets including 2:1 isometric, true isometric, top-down, side view, and first-person. Exports include a packed PNG sheet, Aseprite JSON, and an RPG Maker MZ walking sheet. The tool doesn’t include motions, so users bring their own FBX files, from Mixamo for example. The tool adds a humanoid skeleton, and its interface is in 29 languages.
The press kit lists these prices:
| Period | Price |
|---|---|
| First two weeks of Early Access | $14.81 |
| Early Access | $18.99 |
| Full release | $24.99 |
Two optional steps cost extra, paid directly with the user’s own key: generating a picture with OpenAI, and turning a picture into 3D with Tripo (about $0.30 per model). Those steps are available only in the itch.io edition. The Steam edition leaves out both, and it’s also targeting 23 November, pending approval.
The tool can also connect to an AI agent such as Claude Code or Codex over MCP, and the agent runs the steps for you. The connection is off by default. Blocky, box-style versions of characters work only through an agent, with no button for them in the tool. Roblox is also expanding AI game creation and plans standalone apps.
Robe of Fire’s roadmap lists 3D effects baked into sprites as planned, with paper-doll outfits and text-to-motion under consideration, though the company notes that plans can change.
Miso Editor requires 64-bit Windows 10 or 11 and 15GB of storage.
