Bryce is great but I am still struggling with some of the features. I tried the dome fill light and the square one and it slows the computer so much is difficult to render. I did fine witht he IBL tutorials and the soft shadows, blurry reflections and true ambience but when I tried to apply it to a more complex scene, everything took forever!!

This one is a straight scene and it took 5 hours to render, true ambience look the same but with 5 times extra to render and I finally gave up on the IBL because it crashed my computer. It is still a wonderful program.
