I'm making a room with is rectanular and i can't get the lighting right. Its going to be an underground room with lights coming from above

You'll need to post an image so we can tell what's not right about it.

I have a a wall ground and a ceilling and the lighting get all F%$# up. Any ideas

Impossible to tell without seeing it. Can you post a render?

really depends on what you have in mind..just winging it, I'd say maybe directional lights, if you want a harder focus between light and dark; radials if it just needs to be ambient, etc. We really do need to see what you're doing before we can help..thanks.

You could use a light sphere and surround the entire thing. (Light sphere = a rig of multiple lights set up around the vertices of a sphere.) The celing in your pic would block the overhead part of that but the lateral lights would fill the room well. You would then have to build your overhead lighting into the ceiling...either using radials or spots depening on the effect you wanted. But as the others said a pic would help. The link is to another thread that shows how to use Wings to create a lightdome. I just include it so you can see what I am talking about.

If you are trying to make it dark or one color and you have gamma correction checked bryce will try to undo your changes in the render. If you have sunlight on or link sunlight to view it will affect how thet other lights you load into a scene work, same for the render quality. There's lots of little different windows to open to correct these things plus there are the material settings that affect how your objects react to the light they get. A picture is worth a thousand words. If you post one of your renders we can see what is going on.

Sry for the delay. Hope u guys still read this

Ok, looks to me like: 1. you don't have ANY light source inside the room. 2. you have the ambience up a bit on the material you're using which is helping to cause the loss of definition you're seeing. 3. the only light is the sun ...maybe? Make a couple of radial lights and put them up by the ceiling. Space them in a row midway between the two rows of columns...so kinda of middle of the roomish, use maybe three or four. Turn the intensity on those lights down to about 4 - 7 max. Then on the marble material turn ambience all the way off. See what that looks like.

Turn off cast shadows for the roof and decrease its ambience. The sun will shine through. Light source 1. Add radials and spots accordingly. Click link to see this technique in action in our daily comic. Mitch
