EsskaEsska Global Wind for VRChat
- ダウンロード商品¥ 480
Esska Global Wind simulates wind in VRChat. The wind effect will be applied on GPU with a supported shader. This works for every object in the scene and for every avatar! This package contains the required prefabs for world creators and shaders for everyone who wants that a mesh reacts to wind. lilToon shader is supported with a patcher. NEW: Local wind sources supports AudioLink!
How it works
A world contains a manager script which sends all necessary wind data to the shaders. This data will be sent as global shader parameter, which reaches every shader in the scene.
Shader package
This package can be used for avatars & worlds. Shader types: ・Standard (opaque, cutout, transparent) ・Standard Translucency (opaque, cutout) ・Basic Toon ・Basic Toon Outline ・Unlit Wind settings: ・Fallback wind (for worlds without wind) ・Control influence of wind ・Control displacement by texture or vertex colors ・Normal modification A shader include file allows you to add the behavior to other shaders. Tools for an advanced mesh setup is included with the package.
World package
This package is for world creators. Overview/settings of the components: Global wind source (one per scene) ・Direction ・Wind speed ・Turbulence ・Medium (air or water) Global wind settings ・UI to control global wind speed and turbulence resolution Global wind direction pickup ・Arrow pickup to control the global wind direction Local wind sources (unlimited amount) ・Position/direction ・Wind Speed ・Turbulence ・Medium (air or water) ・Distribution (parallel or radial) ・Shape (none, sphere, cone) ・Falloff (linear, spherical, smooth...) ・Radius ・Override global wind source Local wind pickup ・Attach local wind sources to pickups Local wind toggle ・Toggles local wind sources AudioReactiveLocalWind ・Grows/shrinks the radius of a local wind source based on AudioLink amplitude ・Band ・Gain ・Shrink/grow smoothness
Esska Asset Patcher package
This package can be used to add Esska Global Wind to lilToon shader. Patch available for: ・lilToon 1.4.0 ・lilToon 1.4.1 ・lilToon 1.5.0 ・lilToon 1.6.0 ・lilToon 1.7.2 ・lilToon 1.7.3 ・lilToon 1.8.2 ・lilToon 1.8.3
Demo
You can show how it works in my demo world. There is also a simple demo avatar: https://vrchat.com/home/launch?worldId=wrld_baaf001c-9e99-444e-9680-2fe89c1afe52

Installation
Esska Global Wind: Check the EsskaGlobalWindManual.pdf. Esska Global Wind for lilToon shader: Check the EsskaAssetPatcherManual.pdf I did an installation video for another package. The way, how lilToon will be patched, is almost similar for Esska Global Wind: https://www.youtube.com/watch?v=Jg-VFtrVkPc
