Xuan Yuan Sword 6_DLC_ (bake a hard edge Normal map)

I just finish my project last month. Yes, it's SWD6-DLC ! This time i have some cool challenges. Create a lot of hard-edge model for Environment. Why do i say this is challenge ? Because i didn't much understand the Normal of the Hard-edge and took a lots time to test hard-edge Normal map, let it  looked correctly in Unity .

上個月我剛完成我的專案。是的，它是軒轅劍六-天外之章！這一次，我有一些很酷的挑戰。創建大量的硬邊場景模型。為什麼我說這是挑戰嗎？因為我沒有多少了解法線的硬邊，花了大量的時間來測試硬邊法線貼圖讓它在Unity引擎看起來正確的。

Generally speaking, baking a hard-edge normal.

我將平滑組，設置自動平滑為45度，在3dsmax。

切割UV，取決於不同的平滑組。

Reduce the Gradient of Normal map to avoid the odd shadow in Game engine.

減少法線貼圖的漸層，以避免在遊戲引擎中奇怪的陰影。

As a reminder, this way i test in unity is OK!  Some engine maybe not !

作為提醒，這種方式，我測試Unity引擎是OK！有些引擎也許不是！
