除了BIM的IFC模型(IFC模型 2024.5 已不支持)，目前SaaS Composer僅支援 obj格式。  
(2024年3.4.0版本之後支持 fbx與 gltf格式)

obj模型導入有什麼需要注意的事項呢？

obj模型注意事項:  
一、模型  
(1)模型為可編輯面片  
(2)導出時選三角面  
(3)場景總面數盡量不超過30萬

二、貼圖  
(1)分辨率2的n次方,如256\*512等等  
(2)格式jpg/png  
(3)mtl文件中貼圖僅保留貼圖名稱  
(4)名稱使用英文(勿用特殊字符)  
obj 模型不支持特殊材質，僅支持顏色和貼圖，格式png/jpg格式

盡量將模行簡化能有效的加速渲染及繪製。

想请教一下您，想请问现在 SaaS composer 还支援 Autodesk generate 出来的.ifc format file吗？  
请问我如果有.ifc file 了要怎样import 变成 SaaS 里面的 model/symbol?

ifc，2024.5 之後沒有持續支持。需要轉成其他3D模型格式，再匯入SaaS Composer。

3.4.0之後版本有支持fbx，revit可以導出fbx格式。

您好，请问glb格式的模型导入需要什么注意事项？我将模型导入后，拖入世界就变成全黑的，材质全失效

Lin 您好，  
針對您提到模型導入後呈現全黑的狀況，實際原因可能有很多種，例如模型材質設定、貼圖路徑或導入流程差異等，都可能造成影響。  
由於每個案場的環境可能有所差異，建議您聯繫所在地的產品技術窗口，他們能依據您的專案環境以及實際導入設定，提供更準確的協助。
