there is no option to adjust frequency of the wind in ue4 , if you have small trees in the scene you will get exact wind motion in all of them , but with frequency you can fix this problem , i hope ue4 for add this as soon as possible , its really important thing for wind forces
Hello there,
I’m pretty sure that Wind Directional Source works only with SpeedTree assets, and advanced wind parameters, like oscillation frequencies for different parts of the tree are set for each tree type individually in Speed Tree modeler application.
