Hello,

is there a way to retrieve informations stored in a gltf file thanks to the export_extras=True option of the Export Scene Operator of Blender ?
If so, can we retrieve several of them ? And how to access them ?

My goal would be to include there during export some file hierarchy information used to organize the files in a PostImport Script.
