Hand Script - Tool dev
Maya
Personnal Project
Python
This Python script tool is designed to automate the creation of a flexible and animator-friendly finger rig system. It generates a complete finger control setup with a finger curl and spread attribute, reducing the need for animate individual joints.
Challenges
-
The curl system enables smooth bending of each finger through a single control, driving multiple joints simultaneously while maintaining natural rotation falloff from the base to the tip. This allows animators to quickly pose hands for common gestures such as fists, pointing, gripping, and relaxed hand positions. The curl values can be adjusted globally or per finger, providing both speed and precision
-
The spread system controls the lateral separation between fingers, allowing for expressive hand poses such as splaying, tension, or relaxed spacing. The spread behavior is calculated to preserve anatomical realism, with balanced rotations that avoid joint distortion. This ensures clean deformation and predictable results during animation
The script is fully procedural and reusable, making it suitable for different character scales and hand proportions. By using Python, the tool integrates seamlessly into a production pipeline, enabling rapid setup, easy customization, and consistent results across multiple rigs. Overall, this tool improves efficiency, reduces repetitive rigging tasks, and provides animators with a clean, intuitive interface for hand animation.
