WBV2-P3-004 status

  • task: WBV2-P3-004
  • parent: WBV2-P3-003
  • parity: IO.GLB_ROUNDTRIP
  • implementationClass: LOCAL_EXACT
  • status: done
  • fixture: tests/files/web/generated/WBV2-P3-004-IO.GLB_ROUNDTRIP.blend

Evidence

  • Blender desktop and WASM/Main expose the same bounded GLB roundtrip graph: one mesh with 8 vertices, 12 triangles, one UV layer, one morph target, one two-bone skin, one packed image, and one animation.
  • Export/import preserves mesh, skin, morph, image, and animation semantics exactly; the emitted GLB is 7,540 bytes with glTF magic.
  • Malformed GLB, external image URI, and over-budget input are rejected by the bounded importer. Blender save/reopen remains exact.
