Maybe Chris or Lisa will remember how surprised I was when I first found out that, after spending more than twice the time to create DS versions of my products, I would have to basically give them away for free. And yet, most people will take that for granted, and some would even complain that it was "expensive" to them. Add to insult that it has become increasingly more challenging to create contents, while the prices keep going down. And then when I claim that the market is becoming vendor-unfriendly, there is no lack of people to disagree. <sigh> And yet, I keep doing it because I love it. Those who have left didn't love it enough.Third party vendors are a different story they sometimes do not have the time or the skills to produce products that will work with so many different render engines and if they do, they get very little recompense, if any, for the extra work.
