This product is designed to give you huge Highlands landscapes that can be used for gaming or cinematic purposes.
The goal was to offer you 10 different very detailed environments so that you can model your landscape as you wish.
Added to this are several jungle assets to embellish your scene. The vegetation is generated procedurally with Grass Layers 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.
