The base object will inherit the property table, for every FBX object, if it doesn't exist it will be ignored. The previous code was dangerous and not simple to understand, this makes the code simpler and should result in no leaks with PropertyTable. Features/Fixes: Adds ability for multiple millions of polygons to be loaded. Fixes memory leaks with tokens Fixes memory leaks with property table Fixes loading some corrupt files Fixes meshes not having a unique name to the mesh node. Opens up loading for two more versions: 7100 and 7200, up to 2020. Preliminary support for Cinema4D files in parser now, before this was not possible it would cause memory corruption, which is gone now. FBXProperties not being pointers presented simpler challenges in the long run also, fixed a bunch of bugs.
