使用C#腳本在運行時將游戲物件匯出為FBX

我正在嘗試構建一個房間編輯器。所以用戶已經放置了家具，旋轉它們等。所有物件都保存為 Room 父級的子級。我需要對功能進行編程，現在將房間及其子項保存為 FBX 或 OBJ，以便可以通過任何 3D 查看軟體發送和查看它，甚至可以在攪拌機之類的東西中打開它（紋理還不是問題)

我嘗試使用 Streamwriter，但似乎無法做到。我看過https://docs.unity3d.com/ScriptReference/PrefabUtility.html但這不會匯出預制件，而是將它們存盤在專案檔案中。

有沒有人對我可以用來解決這個問題有任何想法或建議

uj5u.com熱心網友回復：

該FBX SDK系結可以允許游戲在運行時匯入和匯出程序中被執行。

注意：默認情況下，FBX SDK 系結僅為編輯器，不會包含在構建中。為了將包包含在構建中，將 FBXSDK_RUNTIME 定義添加到 Edit > Project Settings... > Player > Other Settings > Scripting Define Symbols。
