Atmospheric Wind Sway
Atmospheric Wind Sway makes foliage react to wind, with gust movement that varies between plants, for players who run NeoForge 1.21.1.
What it does
The mod bridges the wind from Project Atmosphere with the foliage system of SWAY API. Ambient wind is combined with the entity-contact forces SWAY already applies, so plants bend when a player or mob walks through them as well as when the wind blows. Foliage registered through SWAY, including vanilla and modded plants, takes part in the effect.
Gusts near the player move smoothly and stay varied from one plant to the next, so a field does not sway in lockstep. Rain and snow angle with the wind when Project Atmosphere is present, and Simple Clouds provides fallback support. Particle Rain rain can also be angled. The mod is available only for 1.21.1 and is published for NeoForge, with the latest file 1.5.0 for 1.21.1, released 2026-08-21.
Players need the mod on their client, while the server may skip it or add it for extra features. Atmospheric Wind Sway is released under the GNU General Public License v3.0 only, and the source code is open source. Required dependencies are SWAY API and Simple Clouds.
Key features
Wind on foliage
Ambient wind moves vanilla and modded plants registered through SWAY, with the gust effect adding motion nearby.
Entity contact forces
Plants respond to entities brushing past them, combined with the wind so both kinds of motion read together.
Varied gust movement
Each plant moves with a stable offset, so neighboring plants do not sway in unison during a gust.
Angled precipitation
Rain and snow from Project Atmosphere are angled to match the wind, and Particle Rain rain can be angled too.
