Terrain Design Specification for Procedural Landscape Generation This document provides a comprehensive, procedural terrain generation pipeline for the 50km x 30km open-world island map (approx. 1,500 km², comparable to GTA V's San Andreas at ~80 km² land but scaled up for an island focus with denser variety). The design is optimized for game engines like Unity (Terrain system with custom scripts), Unreal Engine (Landscape with Runtime Virtual Textures), or Godot (HeightMapShape3D + custom noise). It uses multi-octave noise functions (Perlin, Simplex, Voronoi, Ridged MF) for realism, biome-blended height modulation, and seamless LOD (Level of Detail) from 4km macro-terrain chunks down to 1m micro-details. Key goals: Visual fidelity to reference art style: Hyper-detailed, painterly landscapes with dramatic cliffs, misty valleys, reflective wet surfaces, volumetric fog, and biome transitions evoking the provided images (Japanese Alps, red rock canyons, tropical beaches, lush villages, neon urban, Mediterranean highlands). Drivability: 500+ km roads (highways, off-road, coastal), with smooth gradients (<15% inclines for cars), bridges/tunnels auto-generated. Performance: Procedural on-demand generation (e.g., Unity's Terrain Streaming), 16-bit height precision, 1024x1024 heightmaps per 4km² chunk (stitched seamlessly). Scalability: Seed-based (fixed seed for consistency), editable via noise parameters. Units: 1 Unity/Unreal unit = 1 meter. Map bounds: X [-25000, 25000], Z [-15000, 15000], Y [0 sea level to 4000m peaks].
