coastal terrain 3d model

Top-down isometric 3D render of a massive 8x8 km square terrain map, optimized as a heightmap asset for further world building. The map depicts a vast, barren coastal environment at a near-future scale. Features include large, rugged, deep gray jagged mountains dominating two adjacent corner quadrants, with steep cliffs. Below the mountains, a massive expanse of dark blue open sea fills the opposite corner quadrants. A smooth, wide, light sand beach separates the terrain. The vast majority of the landscape is a gentle, smooth, empty plain, left untextured for building placement. High contrast lighting to define elevation, high-resolution, low-poly structure, Unreal Engine 5 render style, cinematic lighting, 8k texture detail, game development environment asset."
