Shine Painter — Paint glitter, gloss and patterns onto clothes and hair [VRChat / Unity / lilToon] (Free trial available)

Shine Painter is a Unity editor extension for lilToon materials. Brush clothing or hair in the Scene view, and glitter, gloss or a pattern is added only where you painted. The window can switch between English and Japanese.

No avatar models are included (tool and texture presets only).

Included looks

• Glitter: gold, silver, rainbow, stars
• Gloss: satin, enamel, pearl
• Pattern: gingham, polka dots, lace

Adjust the strength, tint and pattern density.

How it works

While you paint, only a preview is shown in the Scene view; the original materials, textures and meshes are not changed. In the Full version, "Save and use" copies the painted material slots (new files), saves the painted areas as black-and-white PNGs in Assets/KotokotoLab_Output/ShinePainter, and swaps only those slots on that mesh. Even if other meshes use the same material, only the painted mesh changes. One Ctrl+Z undoes the swap (the created files stay). Opening a mesh you saved before lets you continue from the previous painting; saving again makes new files instead of overwriting.

Free vs Full

• Free trial: paint and see it in the Scene view (mirror, eraser and undo stroke included). It cannot save, and the texture presets are 256 px.
• Full: everything above plus "Save and use" (goes into your upload), with 512 px texture presets.

Notes

lilToon materials only (lilToon Lite, Multi, Fur, Gem and similar kinds, and materials with moving UVs, are not supported). Only this mesh's surfaces facing you are painted, up to 2 cm behind the surface under the brush (other meshes in front and see-through parts are not checked, so close cloth layers may be painted too). Areas sharing the same UVs get painted together, and triangles whose UVs span more than two tiles cannot be painted. If the material already uses the glitter (or both MatCaps / both extra textures), replacing it requires ticking "OK to replace the original effect"; this also removes the original effect from unpainted areas (in the copy only). If a gimmick swaps materials with an animation, the animation's material is what you see. PC only. Meshes need Read/Write enabled. The preview appears only in the Scene view. Glitter sparkles depending on the viewing angle. Prefab Mode and Project prefabs are not supported. It does not change meshes or weights. Works without the VRChat SDK and Modular Avatar.

Requirements

Unity 2022.3 (tested on 2022.3.22f1) and lilToon (tested on 2.3.4).

How to install

1. Drag ShinePainter*.unitypackage into the Unity Project window and press Import.
2. Menu: Tools > Shine Painter. The window has an "English" checkbox at the top.
3. Put a clothing or hair mesh of an avatar in your scene into the window, pick a look and paint in the Scene view.

Importing the Full version over the Free trial replaces it.

Terms

Personal and commercial use are both OK. You may distribute or sell outfits and avatars that include materials made with this tool (including the copied preset textures they use), as part of those materials; the original avatar, outfit and material terms still apply. Do not redistribute or resell the tool itself or its texture presets, and do not distribute the presets on their own. Use at your own risk.
