The Poser team generally does not alter bad node behavior because they know people have tailored the shaders to deal with whatever they do. They usually just add new nodes, or add flags or choices to existing nodes to select the new behavior. An example is the noise type, Original or Improved.

Of course, it is a problem that "Improved" is still terrible. I see obvious repetitions and obvious rectangular grids in many of the supposedly "pseudo-random" nodes.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
