It seems when I view my lighting in the Texture Preview mode it is quite a bit different than what it actually is when I do a full render. The problem with that is it takes 30 or so minutes for my scene to fully render only to find that the lights were too low and need adjustment and then through go through the lengthy process again.

I have poser 8.

Is there a way of getting a good idea of what the lighting is like rather than having to go through the time consuming full render?
