Meat Machine is a Geometry Nodes-based toolset designed for rapid anatomy generation and character sculpting block-ins. By utilizing Blender's curve draw tool, users can generate various anatomical structures directly in the 3D viewport. The suite includes specific modes for creating single bones, chain bones for spines or tails, and segmented or sheet muscles complete with UV mapping and tendon controls.

The tool features gestural volume blocking through a blob mode, allowing users to quickly establish basic forms. Additional procedural options include eyeball generation, capsule shapes, and a system that instances object collections along a drawn stroke. The system supports native Blender curve controls like twist and scale for precise shaping of the generated geometry.
