"so ,the question is, who would write said tutorials, if it falls outside the scope of our experience?" That's the thing, really. We all have different areas of expirience. Some people may be wizards with terrains and lattices, while others have focused more on lighting, or specialize in skies and atmospherics, or maybe there's someone out there who's mastered the Tree Lab that confounds me so. I'm just suggesting that perhaps we can pool our knowledge more than we have done so far. I know there must be certain questions most of us have pondered, and that someone here could answer, but just hasn't gotten asked yet, or some great technique that someone has perfected, but hasn't shared because it never occured to them that anyone would be interested. We're all interested in a GOOD Bryce 5 book, but what is it we're really hoping to learn from it? What questions do we want it to answer? What information are we looking for? If we can figure that out, I'm betting we can answer those questions here and get that information from our own.
