Hi Ivan, after playing some more with the function you posted I noticed that If I extract ZYX rotation from a standard Nuke card, and the cards scaling is not uniform on x,y,z, the extracted z-rotation is a bit off. This might be totally expected due to some matrix math that I don't really understand, but any chance you have an idea why this happens?
