Runtime infinite terrain for Unreal Engine 5 — now with hydraulic erosion for dramatically more realistic landscapes. V1.2 adds particle-based droplet simulation that carves natural valleys, sharpens ridges, and deposits sediment — running entirely on the background thread with zero game thread cost. No loading screens, no baking, no pre-built heightmaps. Drop one actor into your level, assign a material, hit Play.

────────────────────────────────────────
🚀 WHAT'S INCLUDED
────────────────────────────────────────
✔ Infinite chunk streaming — actor pool, no spawn/destroy overhead
✔ Fully async mesh generation — game thread never blocked
✔ Layered noise stack — Perlin, OpenSimplex2, Cellular, Ridged Multi, Domain Warp
✔ Continental masking — mountains only appear where land is
✔ Biome blending — blend weights baked into vertex colors (Grass / Rock / Snow / Beach / Underwater)
✔ Foliage system — HISM scatter on thread pool, driven by BiomeFoliageAsset data assets
✔ Dense grass system — ISM ground cover on radius-based world-snapped grid
✔ Per-asset grass radius, resolution, density, slope, collision control
✔ Slope Sink Depth — auto-corrects floating blades on slopes
✔ Hydraulic erosion — particle droplet simulation carves natural valleys and ridges (NEW in V1.2)
✔ Configurable erosion: Droplets, Strength, Deposition, Inertia, Sediment Capacity, Brush Radius (NEW in V1.2)
✔ Water plane with configurable update interval
✔ Seamless chunk normals — no visible tile seams
✔ Full C++ source included
✔ Verified on UE 5.4, 5.5, 5.6, 5.7
