Dave I've just been having simaler problems with a prop I've built. Everything looks fine in my modeler, but when I get it into poser and render, I get holes just like that. I've traced the problem to 2 different stages. The first seams to be a problem I introduced when I put the model into lightwave and reduced the number of poly's. The second is how the model was converted to obj. This problem had me crying for over a week, before I said sod it and went with my high poly source model. In the end I just used the free version of painter 3d that came with poser to convert my model before running it through uvmapper. Problem number 3 looks just like parts of the poly reduced version of my model. In my case I think, it was an artifact of the poly reduction process. What kind of process you went through to get your model in poser ? Don't know if this is any kind of help, or just going off on a long tangent. Thats life when your borde at work. Kris
