StrandKit is a modular asset library for generating and styling hair, fur, and feathers in Blender. It provides drag-and-drop geometry node systems for applying grooms to characters and creatures, covering hair types from straight 1A to coily 4C. The library includes distinct systems for fur types with built-in shading controls for elements like wet and dry zones. Additionally, the package includes tools for converting meshes into hair cards, optimizing grooms for real-time workflows. It features over 1,000 unique hair cards with diffuse, roughness, specularity, normal, start mask, and depth textures. Scattering tools allow users to apply these cards directly to grooms with control over alignment, clumping, and texture settings.
