Yocho II — Night Butterfly Tattoo (B) — a Japanese-style tattoo for VRChat avatars (3D data).

One design, "Night Butterfly B (butterfly and crescent moon)". The included Unity tool generates a thin overlay mesh that follows your avatar's skin. A transparent PNG for lilToon decals is also included.

■ Checked inside VRChat (v1.0.0)

Checked inside VRChat on one in-house avatar (private upload): the menu, the blink, fit on the skin at the back / upper-arm / shoulder positions, flicker, mirrors and sync for other players. Other avatars and other body-part presets are unverified (details below).

■ At a glance

- One design. Shown on the right upper arm (outer side) in the images (0.08 m); it can be placed elsewhere too

- Can also go on your back (see "On the back")

- The overlay mesh is generated on your own avatar (the body mesh is not modified)

- Expression menu "大正タトゥー" → 表示 / 光る / ゆっくり明滅 (Show / Glow / Slow blink). Synced and saved, 3 bits, added automatically by Modular Avatar. The menu labels are in Japanese.

- Note: "ゆっくり明滅" (Slow blink) works only while "光る" (Glow) is on. Glow off = no glow / Glow on + Slow blink off = steady glow / Glow on + Slow blink on = blinks in a cycle of about 3 seconds.

- Transparent decal PNG and glow mask (1024×1024) included

- PC only (Quest / Android not supported)

- AI-Assisted (made using AI as a tool)

■ Design

A symmetrical navy-and-yellow butterfly with a navy crescent moon and drops above, small yellow butterflies around and swirling scroll ornaments below. Glow: the wing veins and edges glow; the moon glows as an outline only; the small butterflies do not glow.

■ A vs B

Night Butterfly comes in two designs, A and B, sold as separate items. This item is B.

A: blue and gold, pale orange moon; ornate with many lines and large sweeping hind wings. B: navy and yellow, navy moon and drops; symmetrical, fewer lines, scroll swirls below.

■ On the back

Besides the right upper arm (outer side), this design can also be placed on the back. It was photographed on the back in the Unity Editor at 0.16 m (see the back images). In the VRChat check, Tsuru (another item) was the design placed on the back. On the back the triangle count goes up: approx. +412 on Kaen at 0.16 m (412–612 at 0.16–0.24 m).

■ What has been verified (v1.0.0)

Verified (one in-house avatar "Kaen"): in the Unity Editor, generation and the NDMF build check (no errors; the "大正タトゥー" menu and 3 synced parameters are added) and how this design looks in stills and video. Inside VRChat (private upload; 5 designs on the back, both upper arms and both shoulders, merged into one mesh and one material): switching Show / Glow / Slow blink and how the blink looks in dark and bright worlds; fit on the skin at those positions (no floating or steps); no flicker or slipping when walking or moving the arms; mirrors; sorting with hair and clothes; use together with the "ピアスの光" menu of the Moon / Plum pierce items; sync as seen by other players, and settings kept after rejoining.

Unverified: avatars other than Kaen / other body-part presets (waist, chest, forearm, thigh, calf, etc.) / generating from the tool window in your own environment / importing several single-design packages together / versions other than those listed below.

■ Placement

Body shapes differ between avatars. In the tool, pick a body-part preset (back, waist, chest, shoulder, upper arm, forearm, thigh, calf), adjust the position with the orange box (projector) in the Scene view, then press "生成する" (Generate). Generate again after moving it. Images: "right upper arm (outer side)", 0.08 m. See the included guide.

■ Requirements

Unity 2022.3 (2022.3.22f1) / VRChat SDK - Avatars 3.10.5 / Modular Avatar 1.9 or later (tested with 1.18.7) / lilToon (tested with 2.3.4) / PC VRChat only.

Not included: VRChat SDK, Modular Avatar, lilToon (install them with VCC).

Your avatar needs a VRC Avatar Descriptor, and the skin where you place the tattoo must be on a single Skinned Mesh.

■ What you get

TaishoTattoo_yochou_b_v1.0.0.zip

- unitypackage (design and generator tool)

- Decal PNG zip

- 導入手順_ReadMe.txt (setup guide) and 利用規約_Terms.txt (terms of use), Japanese / English

3D data only; nothing is shipped. No avatar or outfit is included.

■ Setup

1. Import the unitypackage into a VCC project that has Modular Avatar and lilToon

2. Select your avatar placed in the scene and open Tools → 大正タトゥー → 生成ツール (do not work inside Prefab Mode)

3. Select the body mesh and check only the skin material slots

4. Pick the design "夜蝶 B(蝶と三日月)" and a body part, press "追加" (Add), then adjust the position

5. Press "生成する" (Generate) → check in Play mode → upload as usual

■ Decal without the tool

Put the transparent PNG into lilToon's Main Color 2nd / 3rd on the skin material and use it as a decal. It may be cut at the body's UV seams, and it does not glow.

■ Performance (VRChat SDK performance stats, Unity Editor, PC)

One design: Skinned Mesh +1 / Material slots +1 / Triangles approx. +181 (on Kaen's right upper arm (outer side); varies with the avatar and size) / Texture approx. +2 MB / Parameters +3 bits / PhysBone 0

On the back: approx. +412 triangles (Kaen, 0.16 m; 412–612 at 0.16–0.24 m).

Generated together with other designs on one avatar (default): Skinned Mesh and material slots +1 in total (4 designs on Kaen: triangles +1,050, textures +8 MB).

■ Notes

- Not a physical tattoo or sticker.

- Images and the video were captured in the Unity Editor (inside VRChat, the look changes with world lighting). The bloom in the video is an editing effect.

- The light lines, halo and sparkles in the thumbnail (first image) are image effects.

- Because it uses a transparent material, the draw order with other transparent parts (such as semi-transparent hair) may break (checked with Kaen's hair and clothes in VRChat; other avatars and effects unverified).

- The generator window shows "v0.1.0" in its heading; this is the tool's internal number. This item is v1.0.0.

- The text in the images is in Japanese / English.

■ About AI use (AI-Assisted)
