🌘 功能有時比 Bug 更糟(Sketchfab 教訓)
➤ Sketchfab 處理模型的方式破壞了資產的原始結構,導致嚴重的渲染問題

作者分享了從 Sketchfab 下載的 .usdz 模型,在 Apple 內建檢視器中正常顯示,但在 Blender 中卻出現角色翻轉、物件分離和姿勢重置等問題。經過調查,問題根源在於 Sketchfab 處理模型時,會改動其內部結構,將網格重新打包並添加額外的包裝層,導致模型結構與創作者原始建立的結構不同,進而引發 Bug。作者認為 Sketchfab 的做法雖然出於統一結構的優化考量,但卻犧牲了使用者的透明度和確定性,是一種不良的解決方案。他強調,平臺應允許使用者以原始形式分享資產,而非經過處理的版本,並以 3DWay 的經驗為例,說明即使結構複雜,仍能維持模型原始樣貌。他也推
