Touch Snow - Snow Swirls Where You Are Touched | VRChat contact effect, 4 colors

Touch Snow for VRChat: snow swirls out from the spot where your avatar is touched. 4 colors (Snow White / Ice Blue / Aurora / Gold White).

* The mannequin and the small dummy hand in the images are for the shots and are not included.

A "snow swirls where touched" effect for VRChat avatars. When another player's hand touches your head, shoulders, chest, back, belly or hands, snow swirls from the touched spot (designed with VRChat's standard contacts; not yet verified in VRChat itself). It supports Modular Avatar: just drop the prefab directly under your avatar.

How it swirls (in order from the touch)

• A small flash -> powder snow (up to 64, about 1.2-2.5 cm) scatters -> snow crystal shards (14, 4 kinds, about 3.0-5.5 cm) spin and slowly fall
• Touching continuously gives one burst only. Release and touch again to repeat. Touching a different spot while holding makes that spot burst too
• Your own hand on your own body does nothing by default (turn it on in the menu)

* Reacting spots (8): head (top), left/right shoulder, chest, back, belly, left/right hand

• Head and shoulder zones are close, so touching a shoulder can also trigger the head (a design note)

* Colors: 4 (Snow White / Ice Blue / Aurora / Gold White). Colors differ only in particle color; shape, size, motion and load are identical

* Menu (Expression Menu): "Touch Snow": snow on touch (on/off, default on), respond to own hand (default off). The state is saved

* Load (VRChat SDK in Unity; prefab alone; same for all colors)

• Particle systems 3 / max particles 79 / Contact 14 / Constraint 1 / 2 synced bits / textures about 1.75 MB / no meshes (triangles, bones, PhysBones are 0)
• Standalone Performance rank: Good (PC only; Quest/Android not supported). PC "Good" allows up to 16 contacts, so an avatar that already has 3 or more contacts may fall to Medium or lower in total

Included

• touch_snow.unitypackage (4 color prefabs + materials, textures, FX), Readme (JP/EN), setup guide image, license (JP/EN), changelog

Requirements

• Unity 2022.3 / VRChat SDK Avatars 3.10+ / Modular Avatar 1.18+ (required)
• A humanoid avatar set up for VRChat. PC only. lilToon is not needed
• Tested with Unity 2022.3.22f1, VRChat SDK Avatars 3.10.4, Modular Avatar 1.18.7
• Made for a humanoid of about 1.675 m. On avatars with different bone orientation you may need to adjust the Anchor and Rcv positions/radius inside the prefab

Setup

1. Install Modular Avatar, then import touch_snow.unitypackage

2. Drag ONE color prefab directly under your avatar in the Hierarchy

3. Check with VRChat SDK Build & Test, then upload

• Do not put two colors on the same avatar (no error, but both colors appear at once)

What was verified (facts only)

• In Unity: imported into a buyer-like project; 0 compile errors, 0 NDMF errors, SDK build preprocess passes (all 4 colors)
• In Unity Play Mode, the chain from the SDK contact (dummy hand) to the particles was confirmed (head, right shoulder; Snow White prototype)
• NOT yet verified in VRChat itself (how other players see it, steps/stairs, different avatar sizes)
• On bright floors or white snowy worlds the particles look faint (additive blending; designed against a dark floor)

Terms (summary)

• Modification is free / Redistribution is prohibited (as-is or modified) / Using it on your own avatar uploaded to VRChat is free
• Use as AI/ML training data is prohibited. See License_EN.txt
• The particle images were created without generative AI
