Currently, I'm finishing up a few things in Carrara 2.0, even tho' I've got 4.3...and, yes, it does it with the other functions I've tried like Noise Factory, and a few others. Since I posted the above threads, I've had some success by deleting all the Master Shader entries in the Sequencer, then creating a new Master Shader, and when I have what I want, drag it immediately to the Browser and re-name it. Then apply it to the object. But this seems like the long way 'round.
