Stage 2 shapes the strands Stage 1 produced. Nothing here is destructive: a modifier can be disabled, reordered or removed at any point without rebuilding the layer underneath it.
How the stack works
Select a Hair Layer to open its Modifiers stack. Modifiers evaluate top to bottom, and the viewport updates as you change them.
Select the layer
Pick the target Hair Layer in the panel hierarchy to display its chain.
Add the modifiers you need
Click + Add Modifier and choose from the gallery —
Clumpfor clustering,Noisefor organic jitter, and so on.The Add Modifier gallery. All 11 kernels are available on any layer; the reference table below explains what each one does. Order them deliberately
Drag slots to change the sequence. Shape-forming modifiers such as Bend and Curl belong before detail modifiers such as Frizz and Noise.
Dragging a Noise entry to a new slot. Order is the difference between organic clump shapes and stray flyaways — the same two modifiers, swapped. Scope by group where you need to
Set a modifier's group ID to restrict it to strands in that root group, leaving the rest of the layer untouched.
The mask trigger menu, which limits a modifier to part of the layer.
Order and group scope
Changing slot order updates the output immediately. Setting the groupId selector on a modifier restricts its effect to strands belonging to that root group — so you can bend the bangs without bending the side locks.

| Control | Engine Behavior | Practical Use |
|---|---|---|
| Add Modifier | Appends a new modifier slot to the active layer's pipeline. | Build shape, wave, clump tightness, and silhouette step-by-step. |
| Enable / Disable | Toggles slot active state without resetting parameter values. | Instantly isolate and test individual modifier effects. |
| Reorder Slots | Swaps modifier positions in the execution sequence instantly. | Order matters: e.g. apply Noise before Clump for organic clump shapes, or after Clump for stray flyaways. |
| Group Scope | Filters modifier execution to strands matching a specific Group ID. | Isolate effects to specific root groups (e.g. bend bangs without bending side locks). |
11 modifier reference
Every modifier supports the common controls — Intensity, Scale, Region Start and End, Root and Tip weight curves, Seed and Randomness — plus the specialised parameters below.
Scroll horizontally to view all columns.
| Modifier | Specialized Parameters | Range / Units | Technical Effect |
|---|---|---|---|
| Intensity, Scale, Seed | [0, 5], Scale [0.1, 10] | Applies 3D Perlin vector displacement along strand normal/bitangent frames. | |
| Radius, Frequency (Scale), Scale Variation, Phase Acceleration | Radius [0, 2], Scale [0, 20] | Helical spiral displacement updating lateral frames. Scale variation alters curl size per strand. | |
| Attraction Power, Clump Count & Splay, Splay Start T, Tightness, Tip Preservation | Count [1, 16], Power [0.5, 4.0], Splay [0, 1] | Pulls surrounding strands toward central Voronoi guide centers. Tip preservation uses a cubic ramp (t³) to keep tips aligned while splaying mid-lengths. | |
| Tip Width Ratio, Curve Profile | [0.0, 1.0] | Narrows strand width profile towards the tip. | |
| Octaves, Roughness, Amplitude, Occurrence, Clump Awareness | Octaves [1, 8], Roughness [0.01, 1.0] | Fractal Brownian Motion (fBM) high-frequency jitter. Clump awareness attenuates frizz inside tight clumps. | |
| Intensity, Droop Curve (Scale) | Intensity [0, 5], Droop [0.1, 5] | Pulls strand points downward along local gravity vector via non-linear polynomial droop. | |
| Signed Intensity, Angle Degrees | Signed Intensity [-2.0, 2.0], Angle [0, 360°] | Bi-directional longitudinal bending. Supports negative intensity for reverse bending along local bitangent/normal planes. | |
| Braid Radius, Frequency (Scale), Slot Phase Offset | Radius [0, 2], Freq [1, 20] | Interweaves strands into 3-strand helical plait structures with 120° slot phase offsets. | |
| Cutoff T Threshold, Random Cutoff | T [0.0, 1.0] | Truncates strand length beyond specified normalized distance threshold. | |
| Smoothing Iterations, Blend Factor | Passes [1, 10] | Laplacian neighborhood position filter for reducing harsh angles. | |
| Amplitude (Intensity), Frequency (Scale), Phase Offset, Orientation Angle | Freq [0.1, 20], Angle [0, 360°] | Sinusoidal planar wave displacement angled across local bitangent/normal axes. |
Before you bake
Review layer visibility and the final stack before moving on. The baking engine samples only active, visible layers when it computes texture maps and UV card topology, so what you see in the viewport is what Stage 3 will capture.
