$treesway

When this parameter is added, it will make the material morph around to an env_wind entity to give it the effect that it's blowing in the wind, this effect is used for the trees you see in Counter-Strike: Global Offensive and various foliage seen in Insurgency 2014.

The effect assumes that the model is facing upwards, and the commands specify how much it should be affected by the point entity env_wind

Requires VertexLitGeneric.

Note:This parameter only works in and other games based on it like .

Additional parameters

$treeSway <bool>

Turns the effect on or off.

$treeSwayHeight Float

The height in which the effect is applied.

$treeSwayStartHeight Float

The height from the origin in which the effect starts blending in.

$treeSwayRadius Float

The radius from the origin in which the effect is applied.

$treeSwayStartRadius Float

The radius from the origin in which the effect starts blending in.

$treeSwaySpeed Float

The speed multiplier of large movement such as the trunk.

$treeSwayStrength Float

The distance multiplier of large movement such as the trunk.

$treeSwayFalloffExp Float

The falloff of the effect on small movement such as the trunk. Higher means a more stable center.

$treeSwayScrumbleSpeed Float

The speed multiplier of the small movement such as the leaves.

$treeSwayScrumbleStrength Float

The distance multiplier of the small movement such as the leaves.

$treeSwayScrumbleFrequency Float

The frequency of the rippling of a sine wave in small movement such as the leaves.

$treeSwayScrumbleFalloffExp Float

The falloff of the effect on small movement such as the leaves. Higher means a more stable center.

$treeSwaySpeedHighWindMultiplier Float

Speed multiplier when env_wind triggers a gust.

$treeSwaySpeedLerpStart Float

Minimum wind speed in which a gust triggered by env_wind will start affecting the material.

$treeSwaySpeedLerpEnd Float

Minimum wind speed in which a gust triggered by env_wind will fully affect the material.
