By improving the wind settings it's possible to achieve these results.
Everything was rendered with unreal engine 4 and 5.
Currently Trees Vol. 3 + 4 contain this 'strong wind type' feature.
The update with the advanced wind settings will be released soon.
For 'Trees Vol. 1 + 2' this feature will be added as well. For technical reasons a little later.
New tutorials soon!
