製作第一人稱遊戲時，如果使用的是現成的角色及動畫，可能會需要把手部獨立出來顯示，某些情況下不要顯示角色的其他部分，以免遮到鏡頭之類的問題。
但是一個模型，要只顯示部分就必須用到材質、繪製貼圖（手部不透明、其他透明），但前提是你要知道這個模型的UV，不然也無從畫起。
今天就來分享我們的處理方法-直接把手部模型拆開。
因為手上剛好沒有FPS遊戲用的角色，就先拿其他角色代替了。在Blender中，可以看到模型是骨架的子物件，也就是說，就算拆成多個模型，還是能受骨架影響（權重不會跑掉）。
這是原本的動畫：
現在選取手部，按P分離物件，將手部模型獨立成一個Mesh。
現在播放動畫，手部還是能順利動作～
就算隱藏手或身體都不會影響。
