// Since we clone all structural nodes from our 3d models,

// the database pager will only see one single reference to
|

// top node of the model and expire it relatively fast.

// We attach that extra reference to every model cloned from
|

// a base model in the pager. When that cloned model is deleted
|
||||
// this extra reference is deleted too. So if there are no
|
||||
// cloned models left the model will expire.
