// We can't adjust the material ref counts any longer since some of the old materials might have been deleted.
// One solution could be that this class allocates an array of material pointers when the buffered method is called.
// This array is then passed into the core object and is used by the core object, i.e., the core object does not allocate the
// buffer itself.
