Why do I load the city model (babylon file 80mb) is not displayed, not error

[yaoge]

Hello:

I downloaded a city model（fbx） from sketchfab (https://sketchfab.com/models/d60778fd8b8f4f5e9ce20f0bc506eaeb). Then, I exported babylon  file through unity3d , but in the babylonjs engine is not loaded, not show error . I thought the model was too big (babylon file 80mb). However, I used the tools (https://github.com/BabylonJS/Babylon.js/tree/master/Tools/MakeIncremental) segmentation babylon file. After incremental load loading, it is still not success, not show any error. I suspect that loading is not success because the model is generated with the cityengine, but my suspicions are unfounded.

Hello this could be because there is no light or no camera in your scene.

Thank you for joining the discussion。 there are  light and camera in scene. 

 

After Incremental loading (all the resources are loaded, the screen is frozen like a picture): 

Incremental loading is not used:

Ok so can you please run scene.debugLayer.show() when the scene is loaded?

You will have a lot of useful tools to help you debug your scene (The meshes tree is important to see how many meshes were exported)

The problem is solved,The reason is that babylon file error, I used 3dmax exported babylon file from fbx. then the engine can load it.
