GNM-Maya is a plugin for Autodesk Maya, the professional 3D modeling and animation software used widely in film and games, that lets artists generate realistic human head models directly inside their Maya scene. It builds on Google's GNM model, a parametric system for describing human heads, meaning a head shape can be defined and adjusted through a set of sliders and settings rather than being sculpted by hand from scratch. The plugin offers several ways to create a head. You can sample semantically meaningful variations, blend between different head shapes, describe a face in words and have it generated from that text description, or fit a head model to match a reference photo. It can also bake the generated head into a rig, meaning it becomes ready for animation, and supports generating many different head variations at once for filling a crowd scene. Installation is designed to be simple: you download the project as a zip file, extract it, then drag one specific Python installer file into an already-open Maya viewport. Maya then walks through a first-run setup that installs a Python environment and downloads the underlying GNM model. On Linux and macOS this requires a working Python 3.9 or newer available on the system, though Maya's own bundled Python can be used as a fallback if that is not available. Once the installer finishes, it has copied everything it needs into Maya's own modules folder, so the original downloaded files can be deleted. The project documents its full feature set, a visual gallery showing what every adjustment slider does to the resulting head shape, and its licensing and attribution details in separate files within the repository, since it depends on Google's underlying GNM model and its own license terms.
