I can't remember if you said you're using Poser 8 or not. If so, and if you're using the IDL, you'll need more than one raytrace bounce for proper GI. I think, assuming Poser 8 is handling it the way I think it is. I don't have Poser 8, so I'm not real sure. Other programs use settings independent of raytrace bounces for GI, but I think Poser is using the raytrace bounce number to determine it.
