First, thanks for the replies. Much appreciated. I did some more playing and tried the one by one import. I think I've located the object causing the problem, although I don't know why it was. That, combined with the number of figures, was probably the problem. g my problem is that I want too many figures in the scene. To anser some of the questions above, I'm importing them as vertex, a polygon per mesh. THat seems to be the only way I can really get the shaders to be right. Grouper is an excellent help for that. As well as grouping all the textures together. ANd I make sure that the Poser textures are saved externally. These files are big enough without all that. I'll keep playing with it. I really want to use Carrera's rendering tools with some of my Poser figures. Thanks again!
