Well, the only thing I can think of is the problem must be with the voctorian street elements, but they render fine without the characters.  I have tried redoing the poser figures with different clothing, different morphs, different skin textures, and all to no avail.  As soon as I hit render, kablooey, drop to windows.  I am about ready to say the heck with this whole scene.  Oh one more thing keeps happening now, when I go to resize the poser elements in C5, I get a memory allocation error, but it does resize and the program doesn't crash, at least not until I try to render it that is.  Has anyone anywhere ever managed to get multiple poser characters to work in C5 without having to jump through 30 hoops?
