- A .usdz model downloaded from Sketchfab appears correctly in Apple's built-in Viewer but is distorted when imported into Blender.
- Sketchfab alters the internal structure of uploaded models, repacking meshes and adding wrapper layers, which can cause issues like flipped characters and separated parts.
- The problem originates from Sketchfab's processing, not Blender's importer or the model itself.
- Sketchfab's approach benefits the company by unifying model structures but reduces transparency and usability for users.
- Forcing models into a unified structure is compared to Steam compressing game textures or a shoe store shrinking shoes, highlighting the negative impact on users.
- 3DWay, where the author is Backend Lead, handles models without altering their original structure, proving it's possible.
- Apple's built-in Viewer handles the model correctly due to its deep understanding of USDZ, a format developed by Pixar and Apple.
