Why does foliage cause frame spikes in Unreal Engine 5 — and how does WorldGen's grass system avoid them entirely? ISM vs HISM, Nanite compatibility, chunk-driven loading, and radius-based streaming explained.

🌍 GET WORLDGEN
────────────────────────────────────────
► Get it on FAB: fab.com/listings/e4e93fbe-9326-40b8-a043-a809f788306a
► Project File: patreon.com/posts/158405820
► Free Playable Demo: patreon.com/posts/156846235
► Documentation: patreon.com/posts/156885289
────────────────────────────────────────
🎮 ALL FEATURES (V1.0 - V1.7)
────────────────────────────────────────
✔ Infinite chunk streaming — actor pool, no spawn/destroy overhead
✔ Fully async mesh generation — game thread never blocked
✔ Dynamic terrain LOD — high-detail near, low-poly far
✔ Seamless LOD transitions — no visible pop-in or seams
✔ Far terrain rendering — ultra-low-poly distant chunks for massive view distances
✔ Layered noise stack — Perlin, Simplex, 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)
✔ ISM foliage system — BiomeFoliageAsset data assets, no BVH spike on chunk load (NEW in V1.7)
✔ Foliage on new chunks — appears as player moves, not just at spawn (NEW in V1.7)
✔ Dense grass system — ISM ground cover on radius-based world-snapped grid
✔ GrassGridSize — fixed world-space spacing, independent of radius (NEW in V1.7)
✔ Grass clustering — natural groupings with world-space-fixed centers (NEW in V1.7)
✔ Near/Far tree pattern — same GridSize = same positions = collision only where it matters (NEW in V1.7)
✔ Per-asset grass radius, density, slope, collision control
✔ Slope Sink Depth — auto-corrects floating blades on slopes
✔ Hydraulic erosion — particle droplet simulation carves natural valleys and ridges
✔ Terrain deformation — sculpt with spherical brushes in real-time
✔ Multiplayer support — terrain streams around all connected players
✔ Dedicated server optimization — collision-only geometry, zero foliage/grass on servers
✔ Per-player gravity delay — applied per player including late joiners
✔ CLMNoise — original noise library, no third-party dependencies (NEW in V1.7)
✔ 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
