LimbKit is a Geometry Nodes tool designed to streamline the creation of hands and feet in Blender. It allows users to place and adjust up to five fingers or toes on a palm or base mesh directly in the viewport. The system automatically merges the digits into the base geometry, generating a continuous mesh without the need for manual bridging or retopology. Users maintain control over proportions, finger length, spacing, orientation, and individual phalanx bends through a non-destructive workflow. The setup requires assigning specific vertex groups to define the sewing points and joints. It is suitable for creating human limbs, creature claws, paws, and stylized designs.
