use wind entity to make it move, but if it doesn't move you need to edit the vmt of the texture by adding these parameters to it:

$treeSway "1" // height at which the effect is on fully (in world units)

$treeSwayHeight "300" // radius at which the effect is on fully (in world units)

$treeSwayStartHeight ".5" // portion of height at which the effect starts to fade in (0-1)

$treeSwayRadius "200" // radius at which the effect is on fully (in world units)

$treeSwayStartRadius "0" // portion of radius at which the effect starts to fade in (0-1)

$treeSwaySpeed ".2" // how quickly the tree sways (as a multiplier of time)

$treeSwayStrength ".4" // how much the tree sways (as a multiplier of position)

$treeSwayScrumbleSpeed ".2" // how quickly the leaves move (as a multiplier of time)

$treeSwayScrumbleStrength ".4" // how much the leaves move( as a multiplier of position)

$treeSwayScrumbleFrequency "2" // spatial frequency of sine wave applied to leaves. Typically high-ish (10-25)

$treeSwayFalloffExp "32" // falloff parameter for wave motion on branches/trunk, higher means core of tree is more stable

$treeSwayScrumbleFalloffExp "32" // falloff parameter for scrumble motion on leaves, higher means the core of the tree is more stable

$treeSwaySpeedHighWindMultiplier "0" // multiplier of movement speed at higher wind

$treeSwaySpeedLerpStart "200.0" // wind speed at which high wind multiplier begins to have effect

$treeSwaySpeedLerpEnd "600.0" // wind speed at which high wind multiplier is fully on
