Open Maya Rigging Toolkit

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.

Rules

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.
