UE5 外包美術準則

  1. 面數愈低愈好
  2. 但第1條有例外，如果在場景中這個物件很大，大到人物貼近時會近距離觀看，
    那上面的細節就會需要用模型去做，再拆UV去繪製
    舉例：
    Image Not Showing Possible Reasons
    • The image file may be corrupted
    • The server hosting the image is unavailable
    • The image path is incorrect
    • The image format is not supported
    Learn More →

    如這個門，遠看沒問題，但近看時就可以看到明顯的鋸齒

    • The image file may be corrupted
    • The server hosting the image is unavailable
    • The image path is incorrect
    • The image format is not supported

    但如果要用貼圖來解決這個問題，貼圖的精度就要拉很高
    拉到4k 8k 才能解決的話，反而不如用模型去處理
  3. 當在處理有反光特效的場景時記得要拉一個 Sphere Reflection Capture在旁邊
    或是 Box Reflection Capture 可以增加質感
    範例圖：
    No Reflection Capture

    這是夜光條的範圍
    沒有發光的就可以拆小一點
    要發光的區塊可以拆比較大
    這樣就可以減少一點鋸齒

  2. 場景物件的Mobility請設定為Static
    這可以節影動態光照的成本

  1. stat rhi 可以查看當前畫面的三角面數
    如果有一個物件的面數特別高，請做LOD
    以這個場景，有樹 251萬面，沒樹 43萬面
    樹就佔了 208 萬面，如果有做LOD肯定能優化不少
