Catharina (Mec4D) does amazing work, no question about it. However, I don't think any of the renders in her gallery are "Cornell Box" renders, and it's those type of renders that Poser has difficulty with. It lights scenes quite nicely that have an image or set background, but the light goes haywire when bouncing around inside a 6-sided architectural interior. That is its' shortcoming compared with other rendering engines I've worked with.

And billy, good luck with your continued posting of 3DS Max GUI screen dumps. :O)
