Digital Tutors Understanding The Basics Of Nhair In Maya

Before diving into workflow, understanding nHair’s architecture is essential.

| Component | Description | |-----------|-------------| | Hair System | A container node that manages all dynamic hair data, including start positions, rest state, and output positions for a set of hair follicles. | | Follicle | A locator-like node that attaches each hair strand to a surface (or space). It stores per‑strand parameters and drives the dynamic curve’s root transform. | | nucleus Solver | The global dynamic engine shared with nCloth/nParticles. Controls gravity, wind, ground plane, and time scale. | | Hair Curve | A NURBS curve (degree 1 or 3) representing the hair’s shape. The simulation deforms these curves over time. | | Active vs. Start Position | Active position: current dynamic shape. Start position: the reference shape (often from styling or modeling). |

| Property | Function | Typical Range | |----------|----------|----------------| | Stiffness | Resistance to bending. Higher = stiffer strands. | 0 – 1 (0.2 for soft hair, 0.8 for bristles) | | Damping | Energy loss over time. Prevents jittery motion. | 0 – 1 (0.05 – 0.2) | | Stretch Resistance | Resists length changes. Crucial for realism. | 0.2 – 1.0 | | Start Curve Attract | Pulls hair back to original shape (like a spring). | 0 – 1 (0.1 for subtle, 0.8 for stiff styling) | | Mass | Heavier hair falls faster and reacts more to forces. | 0.05 – 0.5 | Digital Tutors Understanding The Basics Of Nhair In Maya

Unlike legacy hair systems, nHair uses the same unified engine as nCloth. Understanding the Nucleus Solver is critical. Key parameters include:

Want to make your hair look infinitely better instantly?

Go to your Nucleus node (usually nucleus1). Find Gravity and Gravity Direction. Before diving into workflow

By default, gravity pulls straight down (Y-axis -1). If your character is leaning forward, the hair will fall through their face. The secret is to rotate the Gravity Direction to match the character's world space.
