Hi Karl, There isn't any way for me to know whether you have hit upon a bug or just that the scene graph you are trying to optimize is structured in way that could can eliminate the transforms as I simply don't have a dataset that reproduces it. One of the things that prevent transforms being flattened and then removed is if a subgraph has two parents each with it's own unique transform.
I would add that the Optimizer and all it's parts is a sticky plaster fix for bad scene graphs, it tries it's best to fix bad scene graphs but it can't always do everything that could be done. In an ideal world all scene graph would be built optimally in the modelling software and never need this fix up processing. Robert.
