Camera tip #1: if you can't see anything in the scene your camera has been locked out
If you render and you don't see anything, it's all black or black with some dots, then your camera is outside the space that you are framing. This easily happens if you use the Main Camera and the Studio Cubed. The camera is outside the studio. Poser will allow you to see inside because of the way the Hither value, which “pierces” through the backwall. You can make the backwall invisible or move the camera inside.
