The 3D Asset Pack on the vegetation of the surrounding areas is being prepared and will be available very soon.
You will find foliage altas, soil and tree materials, objects such as pieces of wood, rocks, plants, etc. They will be compatible and ready to use for Unreal, Unity and any other rendering engine. The objects will be available in packs or individually and you will have different texture sizes ranging from 2k to 8k, as well as objects with different levels of detail (LOD).
Here is a first preview, on the Unreal Engine in real time, of our pack under construction.
