This product is designed to give you huge desolate landscapes that can be used for gaming or cinematic purposes.
The goal was to offer you 5 different very detailed environments with real mesh cliffs so that you can model your landscape as you wish.
Added to this are several rocky assets to embellish your scene. The cliff is generated procedurally with PCG depending on what material is painted on the floor to simplify the handling, so you can absolutely change the parameters that suit you for your level: it can be the foliage density, the rendering distance of each assets, or why not add your own assets.
