I think the oddness of the poygon shading is caused by Poser's default rounding/smoothing settings - Poser assumes every form is organic and tries to round it out. I believe the technique for correcting that to maintain sharp edges is called "splitting the vertices" - you can do a search in the Poser forum for the preferred techniques. On importing the hallway into Poser, I also noticed a lot of reversed normals - Unless a facet has vertices numbered clockwise, Poser assumes the facet is facing the other way and the back-sides are invisible. For the pic I posted, I did a quick "cheat" of selecting all the poly's of the hall in the Poser Grouping Tool, spawning a new prop from it, then reversing the normals of all, and leaving the two reversed props superimposed on each other. Kind of a klunky fix, but it worked for a quick render. Good luck! Jerry
