Rigloo

Rigloo is a Component-Based autorigger for Maya

Rigloo Banner

Rigloo was built with the following goals in mind:

  • Allow for fast rig prototyping and iteration
  • Be flexible and support a diverse selection of characters
  • Make rigging accessible without sacrifising flexibility
  • Be adaptive and allow for working off of existing animation data

Rigloo is component based. Rigs are constructed with common rig parts that can be customized to fit each character. This design choice was essential to support a variety of body types, as the rig makes very few assumptions on the construction of the users character. Other tools like HIK and Motionbuilders control rig make strict assumptions on character construction and would not work for the project in mind.

Rigloo is code driven. Rigs are built and attached dynamically, meaning it can fit to any skeleton shape. Additionally this was essential to allow for baking the rig to existing animation data. This means the tool can be used for motion capture cleanup or even animation created with other rigs.

Philosophy

While there are plenty of existing solutions for simplifying rig construction, most will include restrictive assumptions about character design. Tools like Maya's HIK require your character to be humanoid, while others will specify humanoid or quadruped. Rigloo was built as a rigging tool that simplifies the rigging process but does not sacrifice the creative freedom we have as riggers.

As a rigger, I also desired something that I would be able to use to speed up my own iteration time. Often I would like to make a quick rig prototype, but will be restricted in the features I can add in a short amount of time. Complex features such as parent space switching and squash and stretch would need to be omitted unless I spent the time to write a script devoted to them. Rigloo is built to speed up the rigging process while allowing for commonly used and complex features to be added to prototype rigs.

Inspiration

Functionally the tool is inspired by Blizzard's code based rigging for Overwatch, as seen in their GDC 2017 talk "The Animation Pipeline of Overwatch". Visually the tool is reminiscent of Unity's component editor, an engine I have much experience with.

Features

Overview Video:

Rigloo supports the following features:

  • Rig saving/loading
  • Rig baking to existing animation
  • 7 components including:
    • IK component with FK offsets and squash and stretch
    • Spine IK Component with FK offsets
    • Leg IK Component featuring a reverse foot roll
  • Global scale control
  • Component naming
  • Control curve generation with
    • Custom base size
    • Choice of shape preset
    • Optional control curve editing and saving
  • Keyable space switching for every component
  • Squash and Stretch for multi-target components with:
    • Individual stretch and squash control
    • Leaf joint support

For a detailed description of how the tool works, consult the documentation.

Download

The latest release can be downloaded here: https://github.com/obriencole11/rigloo/releases

Installation

Currently rigloo only supports a manual installation:

  1. Extract the 'rigloo' folder into your Maya scripts directory
  2. In Maya's script editor(make sure its a python editor), add the following text and run it:
from rigloo import rigloo_main; rigloo_main.load()
  1. The main window should then appear. You can then use this code to create your own shelf button. A custom icon for adding to a shelf is available in icon/icon-logoShelf.svg
