I should have mentioned that I am actually using TraversalOrderBin and DepthSortedBin in my code. Maybe I just don't understand how the renderbins work. Am I correct in assuming that for example the root node would have several numbered bins, each with the ability to have a depth sorted bin, a traversal bin, and a state sorted bin inside them?
It seems that no matter what I do, the last sort order I set in the hierarchy is the only one that does anything.
