I decided to try and achieve similar results in Bryce as that shown in the link above. Sky: ambient white, sky dome black, shadow intensity 75, haze about 3, sun white Materials: flat color 25 ambience lights: 2 25 intensity squared falloff radials, 1 in front of each window positioned about halfway between the pillar and windows. rendering: true ambience, 64 rays per pixel As can be seen only the walls seem to have picked up some red from the floor. I tried this with just the sun (or even cone light) and couldn't get anuthing even close. What was weird is the back of the column got more light than the side because of it picking up light reflected off the back wall and the corners were even lighter.

Damn forgot the image. :)

That goes with what I was thinking before that the light source is washing out the radiosity effect and you can see the colors better on the darker areas. BTW, Im posting a message in a few hours (still working on it) that will give you another new way to try these effects that should be better and faster that what we have tried so far.

Ok, what method did you use here? Looks like there is one light source directed at it somehow because of the sharp shadow. Did you light it from behind?

There are 3 lights. The sun shining through the windows and causes the shadows on the floor. 2 radials as described in first post. I've tried working with just the sun (or 1 spotlight) but haven't had satisfactory results yet. It'll take some more fiddling. So far the above pic is the closest I've gotten.

Interesting, here's one I did a while back didn't come out nearly as nice as yours. I think i used an ambience of 2 though, which would explain it. Not sure what the lighting was, but the scene reminded me of it.

Forgot to mention soft shadows were also on. Found out with true ambience to get soft shadows you have to have it set for the light (or sun, whichever you are using) and in the premium settings for it to work. Right now I'm conducting experiments to find out how exactly light is working with true ambience. I thought I had it figured until the latest render I'm doing now which I can't explain. Will post when finished but probably won't have time until sometime Saturday. I do know one thing, light isn't reflecting at all. Wherever a light hits (say from a spotlight) that is where the light beam stops. True ambience seems to work on hotspots in some way. You'll see when I'm finished.

It is extremely hard to predict in bryce for some reason... it drives me insane. Just when you think you have it figured, it goes and changes again.
