Okay, I've only got a minute. Whatever kind of light you are using for the sun - sunlight, distant light, spot whatever. Turn it off. Then you can see how much glow is from the fire and if that is causing the weird light on the distant terrain. It looks like there is a small glow on the pants leg, maybe not. You should also make a new file, exchange the Poser figure for a small sphere and upload it here so we can figure out what's happening. It's difficult without being able to see everything that you are trying to do. gotta run.
