Does anyone know how to fix this? The leaves on dynamic trees do not move when I have the shader enabled, unlike the foliage of the vanilla tree.

You need to add the leaves to the shader's foliage file

Вам потрібно додати листя до файлу листя шейдера

Do I need to add a foliage block tag? and to which file in the shader folder should I add this? Sorry, I don't know very well about all this.
