Hair Simulation Plugin for DAZ

Hair Simulation adds real-time inertial and pendulum hair physics directly inside Daz Studio without dForce. While you pose the head, move the figure, or play the timeline, scalp roots stay anchored to the head while hair strands lag behind the motion, swing on a length-preserving arc, drape under gravity, rest outside the neck and shoulders, and sway in live wind.

The hair rigging and morphs stay intact. The plug-in moves the hair geometry on top of your current pose in real time inside the Daz viewport. No long dForce pre-calculation or external software is required.

It works out of the box with both standard polygon/card hair meshes and spline/polyline strand-based hair (Polylines, dForce Strand-Based Hair, FiberMesh) across all figure generations (Genesis, Genesis 2, 3, 8, 8.1, 9, and standalone hair props).

, move the figure, or play the timeline.

Reset Pose snaps the hair immediately back to the current posed position. Enable turns the simulation on and off while keeping the modifier assigned.

Sliders on the pane:

Simulated Length (Tips -> Root)
how much of the hair from tips toward the roots moves (0.05 to 1.00).

Root-to-Tip Smoothness
how smoothly motion ramps up from the locked root boundary to the tips.

Overall Influence (Weight)
overall strength of the hair simulation (0.00 to 1.00).

Preset Short
/ Bob, Medium / Natural, Long / Flowing, Heavy / Thick, or Ponytail / Springy.

Stiffness
how quickly strands return to the posed shape. Lower is looser.

Damping
how fast swinging dies down.

Gravity Drape
how far the hair hangs downward under gravity, in centimeters.

Length Lock
preserves strand length so hair swings on a pendulum arc instead of stretching.

Max Offset
the largest allowed offset from the posed hair, in centimeters.

Strand Smooth
keeps neighboring strand vertices moving together without splits.

Stay Outside
pushes hair outside the head, neck, collarbones, shoulders, and chest.

Skin Gap
the gap kept outside the body surface, in centimeters.

Enable Live Wind
Wind Strength, Wind Direction, Wind Turbulence
real-time viewport wind toggle, push distance (cm), angle (-180 to 180 deg), and gusting flutter.

Defaults: Medium / Natural, simulated length 0.75, smoothness 0.50, overall influence 0.85, stiffness 0.22, damping 0.45, gravity drape 3.50 cm, length lock 0.80, max offset 20.0 cm, strand smooth 0.45, Stay Outside on, skin gap 0.80 cm.

What is in the package

Install steps and pane reference.

The plug-in goes into the plugins folder of the installed Daz Studio. Place the DLL directly in that folder. Do not rename it and do not put it in a subfolder.
