Unreal Engine Open World Preview and Landscape Tools
summary
Overview of current Open World work in UE4 with concrete features and tradeoffs: a new Landscape Layer System (4.23 experimental, 4.24 aims beta) gives non‑destructive stacked height and paint layers; Blueprint Custom Brushes (Landmass) let Blueprints render into height/weight maps via GPU Distance Fields but currently render the whole landscape and cost editor memory; Runtime Virtual Texturing enables multilayer blended terrain/mesh sampling; procedural foliage gains exclusion layers; a grid‑based auto sub‑level workflow and file‑per‑actor editing reduce chunking and checkout conflicts. Experimental demos run but need perf and tooling polish.
