Hi , I have been looking for this and thanks to you I found this free hedge , But I am facing a problem . The leaves are appearing to have an extra white layer, The Mesh of leaves have extra default whitish box
You import them like any ressources/mesh/texture you usually import.
You create the materials, connect the textures & their channels to their respective slots & apply them to them meshes, and voilà.
There is nothing special to do.
