Get free Maya character rigging toolset mGear 5.3
Originally posted on 4 September 2025. Scroll down for news of the mGear 5.3 update.
The mGear development team has begun its 5.x updates to mGear, its open-source character rigging framework for Maya.
mGear 5.1 updated mGear’s RBF Manager to improve compatibility with Shapes, Brave Rabbit’s popular blendshape editor.
mGear 5.2 introduces a new system of Blueprint Guides and xPlorer, a Softimage-inspired alternative to Maya’s Outliner.
mGear 5.3 adds a range of new tools, including automated tools for transferring blendshapes between meshes and generating Set Driven Key setups from character poses.
A versatile framework for creating modular character rigs
First released in 2015, mGear was originally based on Gear, Blur Studio technical animation supervisor Jeremie Passerin’s Softimage rigging framework, although it isn’t an exact copy.
It provides artists with a library of customisable rig components for different body parts, and is intended to generate “an infinite variety of rig combinations … without programming knowledge”.
As well as Shifter, the rigging framework, mGear includes a customizable Anim Picker interface, a RBF Manager, and shot-sculpting tool Crank
The toolset has been used by a range of VFX, animation and game development studios: the user reel includes projects by El Ranchito, Mac Guff, Unseen, and Pendulo Studios.
mGear is free and open-source, but lead developer Miquel Campos’s company, mcsGear, provides commercial support and rigging services, which fund development.
mGear 5.1: Update to RBF Manager resolves compatibility issues with Brave Rabbit’s Shapes
mGear 5.1 is a relatively minor update, but it includes quality-of-life improvements, particularly if you use Shapes, Brave Rabbit’s popular toolset for creating and editing blendshape targets.
Both mGear and Shapes use weightDriver, Brave Rabbit’s free Maya node for managing relationships driven through a RBF solver.
From version 5.10, released in late 2023, Shapes has used version 4.0 of weightDriver, which is not backwards-compatible with previous versions.
Since previous versions give better results in mGear, it supported both weightDriver 3.6 and 4.0, but that could cause conflicts with Shapes.
As of mGear 5.1, users can choose whether to use mGear’s own version of weightDriver or an external version, making it possible to update Shapes without issues.
There are also updates to Shifter, making it possible to match FK/IK set-ups to arbitrary limb lengths, and to ueGear, mGear’s new bridge to Unreal Engine.
Updated 28 January 2026: The mGear team has released mGear 5.2.
Highlights include xPlorer, a “fresh alternative to Maya’s Outliner”, inspired by the design of other DCC tools including Blender, Cinema 4D and the much-missed Softimage XSI.
A new system of Blueprint Guides makes it possible to define standardized rig setting that can be shared across multiple characters, with support for per-component overrides.
The Shifter UI has also gone through a “complete overhaul”, and now supports drag-and-drop, JSON-based configuration for file I/O, and comes with prebuilt templates for common tasks.
Updated 7 April 2026: The mGear team has released mGear 5.3.
It’s a varied update – Campos describes it as “our most feature-rich release yet” – adding a range of new tools: both new rigging tools and quality-of-life features.
New Blendshape Setup Transfer tool cuts manual cleanup time
Of the new tools, one of the most significant is the Blendshape Setup Transfer tool – which, as the name suggests, transfers blendshape setups between character meshes.
It automates common, but time-consuming, clean-up processes, rebuilding combination shape networks and removing blendshape targets that exist, but produce no visible deformation.
SDK Creator generates Set Driven Key setups from character poses
Another major new feature is the SDK Creator – the SDK in question being Set Driven Key rather than Software Development Kit.
It generates Set Driven Key setups directly from timeline poses, making it possible to pose a character and have the tool generate the setup, rather than creating it one value at a time.
Since the previous release, mGear has also gotten a Wire to Skinning tool, which automatically converts Wire deformers – often used for shape exploration – to production-ready skin clusters.
Other new quality-of-life tools
mGear 5.3 also adds a number of nice quality-of-life tools.
A new Guide Template Manager provides a browsable library of rig templates with thumbnail previews, which can then be dragged and dropped into a scene.
The new Bookmarks Tool saves, restores and isolates selection bookmarks.
The Matcap Viewer provides a quick viewport material preview using matcap materials.
Now updated to Python 3.13, in line with VFX Reference Platform
In addition, mGear 5.3 moves the software to Python 3.13, as set out in the current CY2026 spec for VFX Reference Platform, removing the old Python 2 compatibility layer.
License and system requirements
mGear is compatible with Maya 2022+, running on Windows, macOS and Linux.
ueGear is compatible with Unreal Engine 5.2+.
The source code for both applications is available under an open-source MIT licence, and the compiled binaries are free downloads.
