Contour Rig Tools vs mGear Framework

Contour Rig Tools is a spline-based rigging system for Autodesk Maya, designed for animation production and technical directors. Contour joint chains generate splines that serve as single deformer influences, potentially reducing weight-painting work. Its volume-aware spline deformation handles bends and twists and is designed to avoid pinching and candy-wrappering. Contour Bones include length and stretch controls, and bone CVs can be used as spline control points. Built-in IK includes stretch and anti-pop features, while constraints drive transforms and relationships between Contour chains. A Python API can create, modify, and query Contour nodes, accepting strings, pyNodes, and MObjects. The tool can drive conventional Maya joints for game-engine export. Version 1.0.12.1 supports Maya 2020 through 2026, except Maya 2023.0, 2023.1, and 2024.0; downloads are provided for Windows, Linux, and macOS. Animator Mode is free for animating with rigs and adding bone CVs. Creating or modifying rigs requires Rigger Mode, starting at $40 a month billed for twelve months.

mGear Framework is a free, open-source rigging and animation framework for Autodesk Maya, built to support character creation for games and animation. Its Maya toolset includes Shifter for modular rigging, Anim Picker, RBF Manager and Python libraries for developing or extending tools. It supports scripting and FBX export. The listed mGear 5.3.5 release is compatible with Maya 2022 through 2027 and is available through the project’s GitHub releases page. For Unreal Engine work, the companion ueGear links Maya and Unreal through automated rigging, asset synchronization, animation transfer, Control Rig generation and camera data exchange. The maker also identifies Unity pipeline integration. Both projects use the MIT license, and rigs made with mGear may be sold and distributed. Free community forum support, bug reports and feedback are available. mcsGear offers paid consulting and services, while its premium support has fixed monthly pricing and a six-month minimum.
