Opaque Sight Housing | A02 — Native Blender Source Editable packed Blender native, original procedural authoring .blend, 2048 × 2048 BaseColor/ORM/Normal maps, native-rendered preview and bounded QA evidence. Native is the appearance reference. ORM red is constant 1, not baked ambient occlusion. No GLB is included in this customer ZIP. Static, fictional, nonfunctional digital exterior art, not working optics or hardware. Blender 4.3.2 stock glTF reimport/reexport changes supplied tangent basis; ordinary N/T HOLD remains (777 pair witnesses; cheek drift up to 13.448 degrees). Nonplanar ornament quad normals and partly unobserved surfaces have bounded evidence, not global equivalence. Native packed .blend is the visual reference. Original source UV was absent on four objects; BakeUV was authored, not preserved. No GLB is included or recommended in this SKU. No game-engine import, repeated round-trip fidelity, rigging, animation, collision, LOD, manufacturing, engineering, safety or fitment certification. The original source scripts were not rerun in this customer repackaging. AI assistance was used for the original asset creation and documentation.
