Roasted Sweet Potato & Steamed Bun - Split It Open, Steam Rises | VRChat

A roasted sweet potato and a steamed meat bun from a winter street stall, held in your hand. Switch between the two with "Meat Bun" in the menu.

Press "Split Open": the top half of the sweet potato falls back, still joined by its skin, and shows two golden cut faces. The bun opens left and right on top of its wrapper and shows the white dough and the meat filling. Thick steam rises from the cut faces.

Each press of "Eat" takes a bite-shaped piece out of it, in 3 steps (about a quarter is left after the 3rd). The 4th press brings it back whole.

Features

• 2 foods in one: sweet potato and steamed meat bun (switch with "Meat Bun" in the menu)
• Split Open: two golden faces on the sweet potato; meat filling and white dough on the bun. Press again to close
• Eat: each press takes a bite in 3 steps, and the 4th press brings it back (the bitten parts show the inside color)
• The steam is drawn with shader planes, not particles: thin at first, thick and dense from the cut faces when split (also visible to people who limit particles)
• Detailed wrappers, 2 colors: a street-stall paper bag (natural paper) or a bamboo sheath. The paper bag has an original newspaper-style print in Japanese and red round stamps, with a folded top and side creases. The bamboo sheath has spots, fibers and a rush-grass tie
• "Wrapper" and "Steam" can be turned on/off in the menu. Hold it in the right or left hand
• Small sound effects when you split, bite and reset it (original sounds)
• 5,598 (bamboo sheath) / 5,064 (paper bag) triangles, 3 material slots, 29 synced bits. No lilToon needed (Modular Avatar only)
• Modular Avatar ready: put it under your avatar and fit it to the right hand

What's included

• FBX, textures (pattern atlas and normal map), 2 custom shaders (food and wrapper, steam), animations, 3 sound effects
• English-menu prefabs (_EN) next to the Japanese-menu prefabs. Use one or the other on an avatar, not both.
• Instruction manual and Terms of Use in English and Japanese

Specs

• Added to your avatar (counted in Unity): bamboo sheath: 5,598 triangles, 3 meshes, 3 material slots, 0 PhysBones, 1 Audio Source / paper bag: 5,064 triangles, 3 meshes, 3 material slots, 0 PhysBones, 1 Audio Source (material slots: food, wrapper, steam)
• Synced parameters: 29 bits
• All counts follow VRChat's rules (hidden parts are counted too) and show how much one prefab adds to your avatar.
• The VRChat performance rank depends on the total with your avatar, so this item alone does not decide it.
• 0 particles, 0 PhysBones, 1 AudioSource
• No extra skinned mesh (splitting and eating are done by the shader)

Requirements

• Unity 2022.3.22f1 (an avatar project made with VRChat Creator Companion)
• VRChat SDK (Avatars) 3.10 or later
• Modular Avatar 1.18 or later
• lilToon is not needed

Please note

• PC only. Not supported on Quest / Android.
• There is no feature for bringing it to your mouth or feeding someone (no Contacts). You eat it with the menu button.
• No hand pose is included.
• The bite step is shared by the two foods (it stays the same when you switch).
• If a viewer's Safety settings turn off shaders, nothing is shown (so the two foods do not overlap).
• The Japanese print on the paper bag is decoration and is the same in the English-menu version.
• The menu actions (break, eat, attach and others) and the sound effects: they move only inside VRChat (including Build & Test) or with Gesture Manager. If they look still in the Unity Editor, nothing is broken.

Terms of use

• You may upload it to VRChat and similar services on your own avatars, edit it, and use it in streams, videos and photos (commercial or not).
• You may not redistribute, resell or share the data (edited or not), or use it to train AI.
• Full text: TermsOfUse_EN.txt in the download (Japanese original: TermsOfUse_JA.txt).

Update history

• v1.2 (2026-10-13): Uploads without pressing Auto Fix in VRChat SDK 3.10 (fixed texture Streaming Mip Maps, mesh Read/Write, Legacy Blendshape Normals). Turned on Load In Background for the sound effects. The shaders support Single Pass Instanced rendering in VR (the look outside VR is unchanged). Manual and description updated (counts are now what the item adds to your avatar, measured in Unity; how it looks in the Editor). The included documents now have English-only file names. The GUIDs are the same as before, so importing it over the old version replaces it.
• v1.1: English-menu prefabs (_EN) and English documents
• v1.0: First release

Also on BOOTH

This item is also sold on BOOTH, the Japanese marketplace.

How this was made (AI-Assisted)

The 3D shapes, materials, shaders and texts of this item were made with scripts written with AI assistance. The sound effects were also generated by these scripts (no recorded or third-party sounds). A person checked how it looks and moves in Unity before release.
