VALIDATOR & FIXER
Checks geometry.json, render controllers and ambiguous or duplicate model names, then auto-resolves the obvious issues — broken references, ambiguities, small details — and flags the rest for you.

ALL THE TOOLS, ONE TOOLBOX
Everything you need for a healthy pack. Nothing that wastes your time.
Each module does exactly one thing, and does it well.
Tools
Catch it, then fix it automatically
Checks geometry.json, render controllers and ambiguous or duplicate model names, then auto-resolves the obvious issues — broken references, ambiguities, small details — and flags the rest for you.
Check and fix skin packs
See your 4D/5D model before exporting
Preview bones, cubes and pivots of custom geometries with the skin applied, rotating live — 4D (cubes) and 5D (poly_mesh), with a built-in renderer.
View and edit models
Preview your classic skin in 3D
See a regular Minecraft Bedrock skin applied to the Steve/Alex model, rotating live, before using it in-game.
View and edit classic skins
Build a pack from scratch
Generates the full skin pack structure — manifest, geometry and textures — without touching a console.
Create skin packs for Bedrock
Turn a 3D model into a working 5D skin
Import an .obj or a 1.12 geometry .json + texture, assign parts to bones, adjust pivots visually, and export a real Bedrock 1.8.0 poly_mesh — ready as a full skin pack.
Convert 3D models to skins
Paint a skin from scratch, live in 3D
A Blockbench-style skin editor: draw on the 2D texture and see it update on the 3D model instantly. Supports 64x64, 64x32 and 128x128, with base and overlay layers, import, and PNG export.

DETAILS THAT MATTER
Built by and for skin creators
🔒
Local by default
Validating, fixing, previewing and building skin packs all runs locally in JavaScript — nothing is uploaded anywhere. The only outside requests are the skin look-ups you ask for in the Skinpack Maker.
🌐
Spanish and English
Full interface in both languages, with automatic browser-language detection.
🧩
Made for 4D and 5D
Not a generic validator: it understands custom geometries, extra layers and ambiguous models.
Open source, as it should be
MBSM is built in the open. Report bugs, request features or check the code yourself.
READY?
Stop guessing why your skin won't load
Open the validator and check your first pack in under a minute.

APPEARANCE
Background
Import a 3D model (.obj) exported from Blender, or an existing Bedrock model (geometry .json, 1.8 or 1.12+ with cubes, box UV or per-face UV), assign its parts to a skeleton's bones, position pivots visually, and export a real Bedrock 1.8.0 geometry (poly_mesh) — ready as a full skin pack (manifest.json, skins.json, lang and textures included).
Suelta tu modelo (.obj o .json) y tu textura aquí
Crea un modelo para empezar
Sube un archivo .obj exportado desde Blender/otro programa, con sus objetos o grupos nombrados (cabeza, brazo, torso, etc.) y una textura.
Cuanto mejor nombrados estén los grupos del .obj, mejor podrá autoasignarlos esta herramienta a los huesos del esqueleto.

ABOUT MBSM
MBSM is a free toolbox for Minecraft Bedrock skin packs that runs almost entirely in your browser: a validator for 4D/5D packs with custom geometries, a 3D skin viewer, a 4D/5D viewer with its own renderer, a Model to Skin 1.8 converter that turns a 3D model (or a 1.12 geometry) into a working 5D skin pack, and a skin pack builder. Your files are processed locally — the only outside requests are the skin look-ups you ask for in the Skinpack Maker.
The goal is to catch exactly the mistakes that usually make a skin not show up in-game, a model fail to load, or textures break — and to make building a pack from scratch simple.
WHAT'S INSIDE MBSM
4D/5D VIEWER
Preview bones, cubes and pivots of custom geometries with the skin applied, rotating live — 4D (cubes) and 5D (poly_mesh), with a built-in renderer.
3D VIEWER
See a regular Minecraft Bedrock skin applied to the Steve/Alex model, rotating live, before using it in-game.
MAKER
Generates the full skin pack structure — manifest, geometry and textures — without touching a console.
MODEL TO SKIN 1.8
Import an .obj or a 1.12 geometry .json + texture, assign parts to bones, adjust pivots visually, and export a real Bedrock 1.8.0 poly_mesh — ready as a full skin pack.
WHAT THE VALIDATOR CHECKS
Geometries
Verifies that the identifiers used in skins.json actually exist in geometry.json.
Textures
Checks that every image referenced by a skin physically exists inside the package and detects upper/lowercase mismatches.
Texts / Lang
Checks that every localization_name has its matching entry in texts/.lang and detects missing or extra keys.
Manifest
Validates UUID, format_version, present modules and other common issues in manifest.json.
JSON
Detects JSON files with syntax errors and shows the approximate location of the problem whenever possible.
Consistency
Compares names, paths, duplicate references and overall consistency across every file in the skinpack.
