V2/ue/Tools/plan-v2-level-world-cooking.py expands V2/ue/Build/Cooking/v2-level-world-cooking.json into deterministic Unreal commandlet commands for world source sets and platform chunk profiles.

Source coverage is .umap, .worldpartition, and JSON world descriptors. Each command collects transitive hard and soft references, writes a reference manifest, generates .v2worldchunk streaming chunks, builds .v2spatial.json spatial indices, and emits a dependency sidecar ending in *.v2deps.json.

Required gates:

  • level-world-cooking-plan-generated
  • level-world-reference-closure
  • level-world-streaming-chunks
  • level-world-spatial-indices
  • level-world-dependency-sidecars

The primary metrics are cook.level.reference_closure_command_count, cook.level.streaming_chunk_count, cook.level.spatial_index_count, and cook.level.dependency_sidecar_count. The CI validator is:
