Strengths
-
First commercial world model with exportable geometry - Proves the feasibility of combining world model approaches with practical asset pipelines
-
Spatial editing via Chisel - Provides designer control through block-out editing before AI style generation
-
Multi-platform output - Outputs compatible with VR headsets (Vision Pro, Quest 3)
Limitations
-
No native navmesh generation - Must be generated in-engine post-export
-
Quality loss in conversion - ~15% visual quality loss when converting splats to mesh
-
Commercial licensing required - $35-95/month for production use

MSF Relevance
World Labs Marble is the first production system demonstrating that world models can produce engine-compatible output. This proves the feasibility of standards for:
- AI generation metadata
- Quality validation profiles
- Neural-to-mesh conversion specifications
Marble represents the target use case for MSF_ai_generation_metadata extension work.
