Omtk is a lightweight suite of production rigging tools for Maya. This include an object-oriented modular autorig solution. Using metadata, generated rigs can be unbuilt and rebuilt if modifications need to be made.

1. Clone the repository or download a release

2. Add this directory to your PYTHONPATH environment variable

3. Open Maya

Alternatively, if you are using rez, a package.py file is included.

The following rules simplify the implementation of the system and must be respected for Omtk to work properly.

• All influences are in a separated hierarchy.
• All joints point toward the X axis, Z is their up axis. This mean the roll axis is always x and the primary axis is z.
• The character should look toward the positive Z axis.
• Feets orientation and straight, always.
• All python code should respect the PEP8 standards.
• All nodes and attributes created in a Maya scene are in camelCase for better integration in Maya.

Omtk vendor the following third party libraries:

A lightweight programming language that create maya utility nodes setup by parsing mathematical formulas.
