PASSFile integrity
5 of 5 GLB files parse with correct chunk lengths
PASSTextures decode, no external links, meshes present
every embedded image decodes; no external URIs; no empty meshes
PASSBase colour texture on every render mesh
LOD0-LOD3 each carry a baseColor texture
PASSUV layout sane (no atlas-spanning faces)
largest UV triangle 10,647 px on LOD0 (limit 25,000), 4,905 px on LOD1 (limit 62,508)
PASSSurface not open or shredded
LOD0 open-edge length 0.72 x model diagonal (limit 1.5); 218 open edges on 29,999 triangles
PASSRe-imports cleanly in Blender at a sane scale
export + re-import keeps 22,495 of 22,494 vertices; largest dimension 1.9042 units
PASSBuyer file set complete
LOD0 is a single mesh; LOD1, LOD2, LOD3 and a convex collision mesh are present
Reported, not failures:
- Not watertight: 13,883 non-manifold edges on LOD0 - normal for AI-generated hard-surface meshes; fine for rendering and games, not suitable for 3D printing without repair
- Separate mesh parts: 709 loose parts on LOD0 - greebles and panels are separate pieces of one mesh; they do not float away from the hull (surface check B5 passed)
- Overlapping faces: 957 intersecting face pairs (sampled) - parts overlap where they join the hull; invisible in renders
- Pivot: the model's lowest point sits at z = -0.132, not exactly on the origin - set the pivot where your engine expects it (centre, base or thrust point)
