  • How to create USDZ file using Xcode converter?

In macOS 10.15 Catalina and Xcode 11 USDZ converter has a rich set of 
commands and supports more input formats for conversion than previous version. 
But before using it you need to download usdz Tools. 
And don't forget to setup a global variables for Python usdz tools. 
Here's how a new command looks like in Terminal:

記錄實作方法： PS: 做圖檔烘培是為了讓輸出的 usdz 模型有顏色

  • 拆 UV 1. 先開啟兩個視窗 2. 右邊視窗切換成 UV/Image Editor 3. 建立UV：左邊視窗點 U -> Smart UV Project，右邊會產生 UV 網格

  • 圖檔烘培 3-1. 選擇要烘培的節點 3-2. 選擇 Edit Mode 3-3. 按 A，全選 4. 命名一個新的圖片名稱 5. 選擇相機（這是 Render 功能） 6. 點 Bake，開始烘培 7. 將烘培圖片儲存 ( EX: alpha.png )

注意: 一定要打燈光，否則烘培出來的圖會一片黑，至少前後打兩盞

  • blender 輸出 obj 檔 ( EX: Alpha.obj )

  • 下載 USDZ 轉換工具

    • USDZ Convert 工具官網下載

  • 執行以下指令，即可產出有顏色的 usdz 檔

    usdzconvert Alpha.obj -diffuseColor alpha.png
