What the tool does
According to the developer's product page, the workflow has seven numbered steps: picture, 3D model, rig, weapon, animate, make sprites, then preview and export. Steps 3 to 7 run on the user's own PC and are free. Starting from your own 3D model or the included sample character means beginning at step 3.
- Rigging: a humanoid skeleton is added automatically. If a joint lands in the wrong place, you can place eight markers by hand (chin, elbows, wrists, knees, crotch) and rig again.
- Weapons: a one-handed weapon, a two-handed greatsword, or a shield can be baked into the sprites.
- Motion: motions are not bundled. You drag in motion FBX files, for example from Mixamo, which needs an Adobe account.
- Cameras: presets include 2:1 isometric, true isometric, top-down, overhead, side view, first-person, and custom.
- Exports: packed PNG sheets with an animation text file, Aseprite JSON, a grid PNG plus JSON per motion, and an RPG Maker MZ walking sheet. Rigged FBX/GLB and STL/OBJ files are also offered.
The developer says it already uses the tool for new enemies in its own game, Fire Field. The Steam listing says a single image goes through 3D conversion, rigging, motion, weapons and rendering to a finished sprite sheet. A Steam community post from Robe of Fire dated 16 October describes the tool as a way to add enemies and animations faster. That is the developer's own account, not independent testing.
Where the sources disagree
Tbreak's headline number is 64 directions. The developer's materials are not consistent about it.
- The product website advertises 1 to 64 directions and shows a 64-direction walk bake.
- The Steam page's "current state" description for Early Access names 8, 16, or 32-direction sheets. Its short pitch and sprite-baking line also say 8, 16, or 32 directions.
- Another section of the same Steam page lists 1, 2, 4, 8, 16, 32, or 64-direction sheets.
Treat 64 as the advertised maximum. Check the build you actually buy before planning an asset pipeline around it.
Local work versus paid services
The developer says rigging, motion, weapons, baking and export run locally with no subscription. Two optional steps involve outside services and the user's own keys:
- Picture generation uses OpenAI.
- Picture-to-3D uses Tripo, at about $0.30 per model according to the developer.
The FAQ says a confirmation dialog appears before each paid call and that you can set a monthly limit. You can skip both steps by importing your own art or a GLB, FBX, OBJ or ZIP model. A sample character lets you try the whole flow without a key.
The privacy claims are the developer's own and have not been audited. It says there is no account, no usage statistics and no automatic crash reports. Data leaves the PC only in these cases:
- the two paid steps;
- when you press Send logs;
- Mixamo searches and downloads;
- a one-time download the first time background removal is used.
The Steam listing says that download is about 930 MB. It also says auto-rigging and background removal use AI models running locally.
Agent control over MCP
Miso Editor can be driven by Claude Code or Codex over MCP. The connection is off by default and is enabled in Settings, under Advanced. The developer says the paid picture and 3D buttons are always pressed by the user on screen.
Tbreak describes the blocky character feature as agent-only. The developer's site now promotes a "BLOCKIFY" button that needs Claude Code or Codex installed and signed in. The site says it takes roughly 5 to 8 minutes per character. Without an agent, the button only shows install links. Check the release build to see how this ships.
Price, platforms and availability
- Price: $14.81 for the first two weeks, then $18.99 during Early Access, with $24.99 planned for full release. The developer says early buyers keep access through the full version. OpenAI and Tripo fees are extra.
- Storefronts: the developer's site names itch.io and Steam for 23 November. The Steam page itself currently lists only "November 2026" and says the software is not yet available. The Steam edition is stated to omit picture generation and picture-to-3D.
- Requirements: Windows 10 or 11, 64-bit, with 15 GB of storage. Steam's minimum is a 4-core CPU and 16 GB of RAM. An NVIDIA GPU with 4 GB or more of VRAM rigs in about 1 to 6 minutes. Without one, CPU rigging takes about 1 to 8 minutes. If neither works, manual marker placement takes about a minute.
- Languages: Tbreak says 29. The product site says 29, while Steam's description text says 28 and its language table says 29 supported languages.
Limits to know about
Steam's Early Access notes are candid about the gaps:
- The tool is built for humanoids. Four-legged animals are not supported yet.
- Hair and cloth do not sway.
- Long capes, robes or long skirts, baggy pants with the legs together, and items held in the hands tend to break rigging.
- A front-facing T-pose is recommended, and an A-pose also works.
The planned full version adds non-humanoid support, swaying hair and cloth, swappable outfits and armor, better rigging and more export formats and camera angles. The developer estimates about six months in Early Access and warns that this may change. Its roadmap lists baked 3D effects as planned, and paper-doll outfits and text-to-motion as under consideration.
Bottom line
For solo and small-team Windows developers who already have 3D models, this is a convenient way to skip manual rigging and render setup. Claims such as "days of work in minutes" are the developer's marketing and have not been independently measured. Bring your own motion files and don't assume 64 directions on day one.
