Description
Turn one versioned Unreal-class scene into aligned camera and physical worlds.
Acceptance
- Preserve asset hierarchy, IDs, transforms, materials, and available semantics
- Export deterministic RGB, masks, depth, intrinsics, and extrinsics
- Run COLMAP mapping, densification, and splat training with retained provenance
- Cook source geometry independently into collision, navigation, and MuJoCo assets
- Measure alignment and run ordinary DimOS camera and navigation workflows

Research direction
The issue names no files, tests, or entry points. Start by locating the existing scene, camera, navigation, and asset-export workflows, then determine how COLMAP, splat training, collision, navigation, and MuJoCo outputs fit together. Done means meeting every listed acceptance item, including provenance, alignment measurements, and ordinary camera and navigation workflows.
