Winter Effects — Frosty breath and falling snow for your avatar [VRChat / Unity / Modular Avatar] (Free trial available)

Winter Effects is a Unity editor extension that adds two winter particle effects to your avatar: Breath (a puff of frosty white breath from the mouth every 2 seconds or so) and Snow (soft flakes and crystals drifting down from above the head). Pick your avatar, choose the effects and the size, and press one button. In VRChat, open the menu (R key on desktop) > Expressions > "Winter" and turn on Breath, Snow or Both. The window can switch between English and Japanese.

No avatar models are included (tool and effects only).

Free vs Full

• Free trial: watch recorded frames of the two effects inside the tool window. It does not include the effect prefabs, and works without Modular Avatar.
• Full: add the effects to your avatar, turn them on from the VRChat menu, remove them, and change the size later.

Notes

The Full version needs Modular Avatar. One Int parameter (KL_Winter, 8 bits), not saved. If the avatar already has a parameter named "KL_Winter", the effects are not added. The mouth position is worked out from the eyes and may be a little off on some avatars. Up to 110 particles and 2 particle systems, within VRChat's PC "Good" rank; other particles on your avatar count too. PC only. Humanoid avatars only. If you change something inside KL_WinterEffects after the tool made it (position, contents, materials and so on), "Remove" does not remove it; the scale of Mouth and Above is the one exception and is treated like the Size slider. Prefab Mode and Project prefabs are not supported.

Requirements

Unity 2022.3 (tested on 2022.3.22f1) and the VRChat SDK (Avatars). The Full version also needs Modular Avatar.

How to install

1. Drag WinterEffects*.unitypackage into the Unity Project window and press Import.
2. Menu: Tools > Winter Effects. The window has an "English" checkbox at the top.
3. Drag your avatar from the scene into the window and press "Add to avatar" (Full version).

Importing the Full version over the Free trial replaces it.

Terms

Personal and commercial use are both OK (streaming and recording OK). Do not redistribute or resell the tool itself (files, textures, prefabs), or give away / sell avatars that include the effects. Use at your own risk.
