alien landscape 3d model

A large alien landscape with broad, playable terrain surrounded by dramatic geological formations. The center of the map should have wide, mostly gentle terrain with rolling hills and large open areas specifically suited for building bases, farms, vehicles, and settlements. Around these open areas, the terrain gradually becomes more extreme, with tall rocky cliffs, deep valleys, strange plateaus, ravines, and massive natural rock formations. The terrain should feel naturally broken and alien, with asymmetrical mountains, unusual ridges, deep cracks in the ground, shallow valleys, crater-like depressions, and occasional elevated rock shelves. Avoid repetitive hills or perfectly smooth terrain. There should be several large flat/low-slope regions throughout the map rather than only one giant flat area. These give players different choices for where to build. Rivers and streams should follow the terrain naturally, running through valleys and around cliffs.
