As with all these situations, DAZ is, of course, in an advantageous position of being able to benefit from the experiences of those who have previously trodden the path. And it has been an encouraging sign that they have demonstrated, even before this thread, an active interest in some of the ideas and discussions mooted. No criticism of CL there for being the pioneers in this area, but circumstances dictate that they really must work hard, and stay on their toes, to keep ahead, now that they are facing the prospect of an imminent and serious competitive threat. Hopefully, the users will win either way. Bill (Taking a brief break from trying to find a common ground on Renderman, PovRay and Poser shading)
