Mazak, not entirely true, you can export the object only if the object isn't locked from export, which should be stated in object description. Locekde to licences and locked from export are 2 different things. An object not locked to a Vue licence may be locked from export.

It's actually useless to buy non locked to a licence objects, unless you want to use the object in another app, when a generic 3D file format is provided, or if the scene is to be shared with users that didn't buy the object.

Don't take for granted the non locked to a licence object is exportable.
