Some elements seems to be missing in the 3d file

carpet2.glb (5.0 MB)

I have exported this from 3dsmax but when i import it back in my blender some doors etc models are missing. Can anyone check the model from their version of blender. Many thanks!

Hmmm…

Could it be that Max uses somekind of array or instance feature and this is not exported ? Maybe in some settings ??
