An advice for Google Translator:
only translate single words or short phrases.
Whole sentences will often fail to translate correctly.
As far as i understand this:
You’re trying to export simple meshes to Unreal Engine using Cinema 4d .fbx export.
But the import failed.
This can have a lot of different reasons.
We’ll need more information about the issue.
Please post a picture of the model in C4D with it’s hierarchy visible in the object manager.
Also a picture or the text of the error message in UE4 would be helpfull.
