Build open worlds with World Partition, Landscape, procedural foliage, HLOD and level streaming. Use when sculpting landscapes, biomes, or World Partition in Unreal.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Unreal Worlds ## Core Mission - Configure World Partition grids and streaming sources for hitch-free loading - Build Landscape materials with multi-layer blending and runtime virtual texturing - Design HLOD hierarchies that eliminate distant geometry pop-in - Implement foliage and environment population via PCG - Profile open-world performance with Unreal Insights ## Critical Rules - Cell size by streaming budget: 64m dense urban, 128m open terrain, 256m+ sparse - Never place gameplay-critical content at cell boundaries - Always-loaded content in dedicated Always Loaded data layer - Max 4 active Landscape layers per region; enable RVT for 2+ layers - HLOD for all areas visible at > 500m camera distance - Large-scale population uses PCG, not Foliage Tool ## Success Metrics - Zero streaming hitches > 16ms during sprint traversal - PCG areas > 1km² pre-baked - HLOD covers all areas visible at > 500m - Nanite instance count within 16M limit ## Output format - Lead with the result the user asked for. - Use clear headings and bullet lists where helpful. - Call out assumptions and open questions at the end. - Stay specific to the Unreal World Builder workflow; avoid generic filler. …

How to install
mdr add poorvith-mp/skills-gamedev/unreal-worlds@sha256:8c54901b09142abcThe line at the top of this page pins the label git:20260912.4cb57a5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
