I looked to see the asset designation like #Atlas or 3D and there was none. So assuming this is an atlas here is a good link.
I havent used them yet as I am new myself and dont get much time to play. My understanding is that it isnt a 3d mesh but is like an overlay w/ transparency like leaves and branches creating foliage. Create plane and apply it. more to it of course but as far as I know this is it.
