MB-Lab for PC: How to Download & Install on Windows

Introduction

If you need a realistic human character for a game or animation but cannot model one from scratch, MB-Lab is the free add-on that builds one for you. It is a free, open-source Blender add-on that creates parametric humanoid characters: you pick a preset, move sliders for age, gender, body shape and proportions, and MB-Lab generates a complete character with skin, hair, eyes and a rig, ready to pose and animate inside Blender. There is no payment, and the download from the official GitHub page is the complete add-on.

This guide explains what MB-Lab is, what it can and cannot do, what your PC needs to run it, and how to download and install it from the official website only. You will also get a first-use walkthrough that takes you from installation to a working result in a few minutes. By the end, you should be able to install MB-Lab on Windows and use it in a real project.

MB-Lab is best for creating realistic human characters for games and animation without modelling from scratch. Because it is free and legitimate, you do not need a cracked copy or an unknown download site. The official website provides the installer, and the free version is a real, permanent tool, not a short trial.

What Is MB-Lab?

MB-Lab is a free, open-source Blender add-on for parametric humanoid characters. In simple terms, it is a tool that runs inside Blender, and instead of modelling a human by hand, you generate one: choose a male or female base, adjust sliders for height, weight, muscle, age and facial features, pick a skin and hair style, and MB-Lab builds the character for you, with a full rig for posing and animation. You can then pose the character, dress it, animate it and render it, all inside Blender.

What makes MB-Lab useful is its realism and its speed. The characters use realistic proportions and anatomically-based morphs, with detailed skin materials, eyes, teeth and hair, so a generated character looks convincing in a render or a game with only a little extra work. It also includes pose libraries and expression controls, so you can put the character into a natural pose in minutes. Two honest notes: MB-Lab needs Blender installed first, because it is an add-on, not a standalone program, and development has moved on to a successor project called Charmorph, so the current v1.8.1 release is the final one. Also note that characters made with MB-Lab carry an open-source licence, so check the licence terms before using a character in a commercial project.

Key Features

Parametric character generation: Sliders for age, gender, body shape and proportions generate a complete human character in minutes.
Realistic proportions and anatomy: Anatomically-based morphs give the characters believable bodies and faces, not cartoon shapes.
Built-in rig for posing: A full rig lets you pose the character and animate it with Blender’s animation tools.
Skin, hair and eyes included: Realistic skin materials, eyes, teeth and hair come with the character, so it renders well immediately.
Pose and expression libraries: Ready-made poses and facial expressions help you place the character naturally in a scene.
Works inside Blender: MB-Lab runs as a Blender add-on, so you keep Blender’s modelling, shading and rendering tools.
Export for games and animation: Export the finished character to game engines and other 3D programs from Blender.
Free and open source: MB-Lab is free and open source, with no trial, no account and no payment needed.

System Requirements

Operating System: Windows 10 or Windows 11, 64-bit
Other software: Blender 4.0 installed first (MB-Lab v1.8.0 is built for Blender 4.0)
Processor: A modern dual-core processor or better
RAM: At least 4 GB of RAM for basic use, 8 GB or more recommended for detailed characters
Storage: Around 500 MB of free disk space for Blender, MB-Lab and your projects
Other: A stable internet connection for the download, and a mouse for working in 3D

These are practical, modern Windows guidelines, not a word-for-word copy of an official specification table. The most important point is simple: MB-Lab is designed for normal Windows PCs, and a modest modern computer is enough to start.

How to Download MB-Lab (Official Method)

The only safe place to download MB-Lab is the official website. Do not download it from random file mirrors or “free download” portals, because those copies may be outdated or bundled with unwanted software. The official site is the source of truth for the current version.

Official download link: https://github.com/animate1978/MB-Lab

On the official MB-Lab GitHub page, open the Releases section and download the latest release ZIP file for Windows to your Downloads folder. Do not extract the ZIP file yet, because Blender installs add-ons from the ZIP itself. There is no account, serial number or payment involved at any point. If a site asks you to pay for MB-Lab, or offers a cracked version of it, leave that site and return to the official GitHub page.

Step-by-Step Installation

Follow these steps in order. Take your time with the install location and component choices, because those are the steps that most often cause problems later.

Install Blender first — Download and install Blender 4.0 from blender.org if you do not already have it.
Download MB-Lab from GitHub — Open https://github.com/animate1978/MB-Lab in your browser and download the latest release ZIP file.
Open Blender preferences — In Blender, open Edit, then Preferences, and go to the Add-ons tab.
Install the add-on from the ZIP — Click Install, choose the MB-Lab ZIP file you downloaded, and do not extract it first.
Enable the add-on — Tick the checkbox next to MB-Lab in the add-on list so it loads when Blender starts.
Open the MB-Lab panel — Look for the MB-Lab panel in the 3D viewport sidebar and open it to see the character controls.
Create your first character — Click the button to create a character and wait for MB-Lab to generate it in the viewport.

Tip: Do not extract the MB-Lab ZIP file before installing it. Blender installs add-ons from the ZIP itself, and extracting it first is the most common install mistake. If MB-Lab does not appear after enabling it, check that your Blender version matches the add-on release.

First-Use Walkthrough: Your First MB-Lab Character

This walkthrough is a simple first project. It is not a full course, but it will help you see MB-Lab working on a real project and learn its main tools.

Open Blender and the MB-Lab panel — Open Blender, then open the MB-Lab panel in the 3D viewport sidebar.
Create a base character — Click create and choose a male or female base character to start from.
Adjust the body sliders — Move the height, weight and muscle sliders until the body shape looks right.
Choose a face and skin — Pick a face preset and a skin material, then adjust the age slider to taste.
Add hair and eyes — Choose a hair style and eye colour from the MB-Lab options.
Pose the character — Use the rig controls or a pose preset to put the character into a natural standing pose.
Render a test image — Set up a camera and a light, then render a test image to see your character.

Is MB-Lab Free?

MB-Lab is free and open source. You download it from the official GitHub page, install it in Blender, and use it without paying and without a time limit. There is no paid version of MB-Lab itself. Be aware of two honest limits: it needs Blender installed first, and the current v1.8.1 release is the final one, because development has moved to the Charmorph successor project. Also check the open-source licence before using a generated character commercially.

That free status is important for this guide. All the steps here use the official download only, and they do not involve cracks, activators or licence keys. If you ever see a site offering a paid or cracked version of the free program, treat it as unsafe and return to the official site.

Frequently Asked Questions

Is MB-Lab safe to download?
Yes, when you download it from the official website only. The official installer is the version made by the developer. Avoid third-party sites that bundle extra software or ask for payment for a free program.

Does MB-Lab work on my Windows PC?
Yes, in most cases. MB-Lab runs on Windows 10 and 11 (64-bit), and the system requirements above cover a normal modern PC. Check the official site for the exact current version if your PC is older.

Is MB-Lab really free, or will it stop working?
The free version described in this guide is not a short trial. It stays usable after installation. There is no paid edition of MB-Lab itself, but it needs Blender.

Do I need a powerful PC to run MB-Lab?
No, not for basic use. A modern Windows 10 or 11 PC with 4 GB of RAM or more can run it for simple projects. Larger projects with many objects and effects will benefit from more RAM and a faster processor, but you can start and learn on a normal home PC.
