Concept → Game Asset

Describe a prop. Get a game-ready GLB — decimated to a tri budget, clean UVs — handed to your engine via a public manifest a community bridge imports. One conversation, lineage kept.

The loop

prompt: "low-poly treasure chest, hand-painted, 3/4 view, neutral bg" → create_media # concept image → tripo-i3d # raw high-poly mesh → refine_3d "game-ready, 5k tris, clean UVs" # blender-headless → optimized GLB → handoff to="godot" # public interop manifest → [Godot bridge imports it] → iterate: refine_3d "lower poly" (lineage kept)

Full lineage — verified live

Every step is linked, so asset_lineage traces the whole story back to the concept image. Run live on prod (2026-06-20, project proj_8339d592f4f0): generate_project concept → import_asset mesh (derived_from concept) → import_asset game-ready (derived_from mesh) → asset_lineage returned the 3-step chain concept → mesh → game-ready. The import_asset verb is what records the concept→mesh edge.

The handoff manifest (interop v1)

This is the entire integration surface — a Godot bridge (infra/bridges/godot/, ~60 lines, no Storyboard dep) reads it and imports the asset.
