Mesh malformed : missing semantic "position" in morph target

Hi,

I was developing a QuickLook extension for viewing SceneKit files.

the file loads fine but without meshes and gives this error in the console: "Mesh malformed : missing semantic "position" in morph target"


the same script used for the quicklook extension works without problems with the exact same file.


Does someone have the knowledge to help me?


Thanks in advance.
