Poser really is giving me a hard time not to hate it tonight. Please looks at this. The picture above is just a screenshot from the scene BEFORE rendering. The picture below is the rendered result of just the scene that can be seen on the photo above. As you can see the broom and the corners of the desks are blown up like balloons. Why does something like this happen? What can I do against it? Why does my poser hate me so much? :(
