Thanks for the expertise. As a Poser newbie, i'm happy to just get a decent looking result from an older costume product. But i certainly appreciate learning the details and "gotcha's" too. What happened in my case was that when i double clicked on the renamed MAT thumbnails, Poser 6 (SR2) offered to create new materials, and when i okayed that dialog, i got a shader setup automatically. No doubt it didn't convert everything, but the material looks quite good, without further work in the Materials room. This is a far foreground figure, so doesn't need the perfection a closeup might.
