Reason of failures

Checked = fixed

• [ ] Nested variantSet Teapot/Teapot_Materials.usd https://github.com/syoyo/tinyusdz/issues/94
• [x] ReconstructMaterialBindingProperties():2168 PURPOSE must not have nested namespaces for 'mateirial:binding' StandardShaderBall/layers/environment.usda
• [x] Comment in Stage meta McUsd/McUsd_10cm.usda https://github.com/syoyo/tinyusdz/issues/138
• [ ] type mismatch: Parsing attribute normals failed. Error: Property type mismatch. normals expects type normal3f[] but defined as type point3f[] normals_types/normalsTypes.usda
  • Expected failure?
• [x] Value block + metadata RelationshipEncapsulationTests/InternalReferenceTest.usda https://github.com/syoyo/tinyusdz/issues/137
• [x] type mismatch: 0 Parsing attribute inputs:st failed. Error: Internal error. Invalid attribute value? get_value failed. in ElephantWithMonochord/SoC-ElephantWithMonochord.usdc fixed via https://github.com/syoyo/tinyusdz/commit/8a5491db31a28b469ec944eba0f157ca62aa0f33
• [ ] LoadUSDZFromMemory():545 Asset no[1] Image width too large UsdCookie/UsdCookie.usdz
  • Expected behavior? Texture width is 8192, and USDZ's limit is apparently set to 2048. https://forums.developer.apple.com/forums/thread/693867
• [ ] doubleSided attribute in Mesh is not qualified with uniform. bool doubleSided = 1 in McUsd/McUsd_10cm.usda McUsd/McUsd_10cm.usdz
