  25         A list of percentages to override the default LOD behavior.  These
  26         percentages are used to determine which lod to use based on screen size
  27         percentage.  If the percentage covered by the node bounding volume is less
  28         then entry 0, we use child 0.  If is is greater then entry 0 less then
  29         entry 1, then we use child 1 and so on. Ex: [0.05, 0.01, 0.001]
