Windy is an addon from SMArchviz for adding wind to a Blender scene. Running Create Wind places a wind system at the 3D cursor location, ready to simulate realistic wind, and Delete Windy removes it from the scene completely. The idea is a realistic wind effect without spending time tweaking many parameters each time you add wind.
The addon puts its controls in a side-panel tab named Windy. Wind Strength sets the intensity in the scene, Turbulence Strength sets the turbulence amount, FreqZ Strength controls the intensity of the wind and turbulence animation, and FreqZ Scale controls its speed. You can save multiple wind presets and switch between them in real time or use them to create animations.
Windy works with Blender 4.0 through 5.1 and is used with the Cycles and Eevee render engines. It is released under the GPL license. Installation runs through Edit > Preferences: install the windy.zip file, activate the addon, and the Windy tab appears in the side panel. A demo video is available.
