Gradient

By the end of this page you'll know how to bake a world-direction gradient into a color texture, and how to set a Reference Bone so position stays fixed even when the pose changes.

Creates: Color UV texture (sRGB) — for ombre/fade dye

Procedure

1. Select object → Load → Preview ON
2. Edit gradient colors or use a preset (white→black, etc.)
3. Use direction buttons (↑ ↓ ← → Front Back) to set direction, or directly drag start/end handles in the scene view (center knob = move everything)
4. Confirm wrap mode (Clamp / Repeat / Mirror) and preview display option
5. Bake — saves as color texture (sRGB)

If the mesh has multiple materials, pick the working slot from thumbnails below the checkbox. → Material Slot Picker

Uses world position

The gradient reads world coordinates. Rotating the camera doesn't change results. For avatars standing in the same spot, applying a preset will reproduce the identical direction and range.

When Preview is off, scene view handles appear dimmed and can't be edited.

Reference Bone

Pose changes shift world coordinates. If an avatar raises its arm, the sleeve's gradient stays at world position, not relative to the body.

Set a Reference Bone and the start/end points follow that bone.

Situation	No reference bone	Reference bone set
Avatar T-pose → A-pose	Position shifts	Stays fixed
Apply preset to different avatar	World coordinates as-is	Finds bone by name and reproduces
Avatar has no bone with that name	—	Falls back to world coordinates

Head for hair, arm bone for sleeves

For gradient on moving parts, pick the bone that actually moves that part. Then pose adjustments won't make the picture flicker.

Wrap mode

What to fill the area outside the gradient range.

Value	Behavior
Clamp	Extend both end colors as-is
Repeat	Repeat the gradient
Mirror	Repeat with alternating direction flips

Saving

• Gradient is color, so it saves with sRGB on. Opposite of masks. → sRGB and import settings
• If a same-named file exists, you're asked Overwrite / New Name / Cancel.
• Confirm in the Recent Bakes list at tab bottom; ping or open folder.
• When Hierarchy selection changes, a "Selection changed — reload" line appears.

Where to assign

Gradient output is color, not a mask. It goes into a color layer slot, not a mask slot.

Shader	Example
lilToon	Main Color ▸ 2nd ▸ Color Texture
Poiyomi	Decal · second main texture family
NiloToon	Base Map ▸ Stacking Layer ▸ Color Tex

To specify "which region gets this color," make a separate mask with Bridge + Region Mask or Paint and assign it to the mask slot of the same layer.
