CoordinateSystem used to derive from the deprecated and removed StateRenderable holding additional transform information for the renderer. A better approach that is also used in Gaffer, the transform information is better stored as separate transform information. Cortex 10.6 also removed all DCC integrations, i.e. IECoreMaya, which stored, for example Locator transformation on the CoordinateSystem. We provide a way to still retrieve this information from old SceneCaches, although not fully transparent and backwards compatible. Clients of CoordinateSystem will need to be adjusted if needed. The `M44fData` is stored as `LegacyTransform` in the `BlindData` of the CoordinateSystem

@johnhaddon Thanks again for giving me pointers for the different approaches. I think the less complex way of reading the matrix directly in Cheers, |
