Yeah, that ZBrush release was a doozy. Were you following that all night? I myself was up until around 1:45 PST, but I'd only bought ZBrush the day before so it wasn't so critical for me. Anyway, about this transparency problem. I really do appriciate your attention to this, and I did try loading your scene and rendering. However, I also got the same results with your scene as with my scene. Are you sure you didn't have antialiasing turned on when you rendered it without the artifacts? In this simple scene the problem is displayed so minutely that the AA entirely removes visibilty to it... I'm still hoping for a resolution to this, but it is starting to look less hopefully. The e-on tech support said to just turn on AA to blend away the artifacts, but while that removes visibilty of them in this sample scene it is not enough for the complex scene I first noticed the problem with. In that scene, as shown in the picture I posted earlier, the artifacts are so large that they discolor the area even with AA. Of course I could clean up in post, but that's not really the point. It looks like a straight-up rendering defect to me, applying transparency to non-transparent objects where they intersect transparent ones... What do you guys make of it?
Thanks again,
Matthew
