    - Only vertex positions are returned, not other vertex attributes.
    - Positions are relative to the origin of the whole model, instead of local to a node.
    - If a mesh is attached to more than one node, its vertices will be in the table multiple times.
    - Vertex indices will be relative to the whole triangle list instead of a mesh.
