Hi Robert and Raymond, I have tested latest changes (rev 7975). Inheritance problem that looked like invisible polygon casting shadow for half of the scene vanished. So far, so good ;-).
IMHO, the problem J-S noticed with ThreadingModeHandler is different. Its not related to inheritance mask changes and does not affect only Shadow example. It can be also seen with Prerender example with RTT camera using FBOs and PixelBuffers. And due to lack of other supects I agree with J-S: we should put the blame on NVidia drivers ;-(.
