More details needed of what you want to achieve:) But here's how I made one of my latest works.. check out the lights fromn that wireframe link. The whole scene is placed inside of a giant tunnel and as you can see from the columns the sun light is coming behind the back. There at the far end is just haze/fog... then it's good to place lights to bring out wanted details more. In that scene I used just few spotlights near the fire and that far wall. Remember that negative light values are also very handy:) And to achieve the final result (in my gallery) I adjusted levels and stuff in Photoshop... also added some dim light rays using difference clouds-->radial blur-->blending technique because my laptop can't handle volume lights straight in Bryce... In outdoor landscape like my latest one "Redhorn Pass" all I did was placing the sun.. no additional lights. I hope this gave some help and ideas:) -Antti-
