All Features

1. Direct Attribute Deformation

• Pure NumPy Vectorized Performance: Hair point deformations evaluate in real-time during viewport playback and rendering.
• Zero Geometry Nodes Overhead: Operates directly on native curve point attributes (position, sk_basis, sk_delta_*) without modifier bloat or tree evaluation delays.
• Session Cache: Dynamic evaluation cache prevents redundant recalculations when values are static.

2. Interactive Sculpt Curves Workflow

• One-Click Grooming: Click Groom '[Key Name]' to enter Sculpt Curves mode immediately on the active key.
• Native Brush Support: Sculpt freely with all native Blender hair brushes (Comb, Snake Hook, Pinch, Smooth, Grow/Shrink, etc.).
• Automatic & Manual Delta Baking: Click Save & Finish Grooming or simply switch back to Object Mode—sculpt displacement is automatically extracted and baked into shape key deltas.

3. Keyframing & Rigging Driver Integration

• Timeline Keyframing: Keyframe Value sliders directly with I or the animate button on any frame.
• Full Driver Support: Right-click the Value slider and choose Add Driver to drive hair shapes from character Armature bones, facial bones, action constraints, or custom properties.
