About This Software

From one 3D model to an animated sprite sheet

Work that used to take days, started with a single button. Rigging, animating, and rendering many directions by hand used to take days per character. Miso Editor is a desktop tool that takes a character's 3D model and walks it through rigging, motion, weapons, and 1 to 64-direction rendering in one continuous workflow. Screen in 28 languages.

The developer is making Fire Field, a 90s-style isometric ARPG on Steam, and the enemies in that game were made with this tool.

Everything runs on your own PC

Rigging, motion, fitting weapons, sprite baking, and export all run on your own PC and work offline. There are no extra fees and no subscription.

• Import your own 3D model (GLB / FBX / OBJ / ZIP) and go straight to rigging

• A sample character and sample weapons (sword, axe, bow) are included, so you can try the whole workflow right away

What it does

• Auto Build: choose your own 3D model or the sample character, and one button takes it all the way to a finished sprite sheet (a one-time setup is needed first: download some free motions from Mixamo)

• Import your own 3D model (GLB / FBX / OBJ / ZIP). Rigged humanoid models whose bone names differ from Mixamo can be imported too (bone roles are matched from the shape, and you can pick them again by hand)

• Auto-rigging: adds a humanoid skeleton automatically, right on your own PC. About 1-6 minutes on an NVIDIA GPU, or it runs on the CPU if you have no GPU. If the auto result is off, you can place 8 markers by hand (chin, elbows, wrists, knees, crotch) and rig again

• Motion: drag in free motion FBX files from Mixamo to apply them to the rig and preview them instantly

• Weapons: give your character a one-handed weapon, a two-handed greatsword, or a shield. The weapons are baked into the sprites. A sample sword, axe, and bow are included, and you can import your own weapon models

• Sprite baking: renders 1, 2, 4, 8, 16, 32, or 64-direction sprite sheets

• RPG Maker MZ export: bake with the RPG Maker MZ camera and it also writes a ready-to-use 4-direction walking character sheet ($name.png, 3x4 frames)

• Camera presets: 2:1 isometric, true isometric, top-down, overhead, side view, first-person, and custom (save your own by name)

• Per-motion and per-character settings: frame count, duration, looping, frame size, sheet width, character height, and facing direction

Output

• PNG sprite sheets plus a text file describing each frame (anim.txt)

• Aseprite-format JSON frame data for each sheet (.aseprite.json)

• A separate grid sheet for each animation (PNG + JSON)

• Everything for a character in one ZIP download

• RPG Maker MZ character sheets

• Rigged 3D models (FBX / GLB), with or without applied motions

What you need

• A 3D character model (GLB / FBX / OBJ / ZIP). You can also try the sample character

• Free motion FBX files from Mixamo: download them with a free Mixamo account. No Miso Editor account is needed

• No other software to install: everything needed for 3D processing and rendering is included

• For auto-rigging, either an NVIDIA GPU with 4 GB+ VRAM, or 16 GB+ of PC memory: with no NVIDIA GPU, rigging runs on the CPU instead (about 1-8 minutes). Manual rigging: if your PC has neither, you can rig by hand. Place 8 markers (chin, elbows, wrists, knees, crotch) on the character

Supported OS

Windows 10 / 11 (64-bit)

Screen languages

The screen is available in 28 languages (English, 日本語, 简体中文, 繁體中文, 한국어, Русский, Español, Português (Brasil), Português (Portugal), Deutsch, Français, Polski, Türkçe, ไทย, Українська, Italiano, Čeština, Magyar, Svenska, Nederlands, Dansk, Tiếng Việt, Bahasa Indonesia, Suomi, Română, Norsk, Ελληνικά, Български)

Who this is for

• Developers who need many multi-direction character sprites for any kind of 2D-sprite game, such as RPGs, action RPGs, roguelikes, strategy games, and shooters. Any view works: isometric, top-down, overhead, side-view, or first-person (classic sprite enemies), or any angle you set with a custom camera

• RPG Maker MZ users who want walking characters made from their own 3D models

• People who have 3D models but would rather not spend time on rigging and render setup

• Anyone who wants smooth 16 or 32-direction facing, not just 8

• Anyone who wants to keep a rigged 3D model alongside the sprites

Please note

• Auto-rigging is designed for humanoid characters (two legs, two arms). Quadrupeds or heavily stylized shapes may not rig well

• Works best with: a front-facing character with legs slightly apart and fingers spread. T-pose recommended (A-pose also works)

• Tends to break: long capes, robes, or long skirts; baggy pants with the legs together; weapons or items held in the hands (add weapons later with the weapon feature instead); arms hanging down at the sides

• Wings, tails, and long hair stay attached to the body and do not sway naturally

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

[AI use during development]
AI coding assistants were used in writing this software's code. The bundled sample character and sample sword 3D models were made with an AI 3D generation service.

[AI use inside the software]
- Auto-rigging: an AI model running locally on the user's PC (nothing is sent externally).
- Background removal: an AI model running locally on the user's PC (nothing is sent externally).
- Manual rigging, motion application, and sprite rendering: standard 3D processing. No AI is used.
The software does not send data to any external AI service. Only when the user turns on MCP (control from an AI app) are results passed to the user's own AI app (off by default).
