The 0.10-ratio collapse tore the generated helmet (holes + fragmentation). Re-imported fresh, welded doubles + recalc normals + deleted loose geometry FIRST, then a gentler 0.18 collapse -> 4198 tris with 0 boundary edges (watertight). Re-exported the static staging GLB; ArtStaging now shows a clean copper Mark-V (bolted porthole, seam ridges, top valve) at head scale. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
