When I render in Poser the skin details of the textures come out very well, but not in Bryce. In Bryce the skin of Poser figures looks so flat and "chalky"? Are there any lighting tips that I can use?

Try using spots & sepherical lights opposed to the straight sunlight George Fronte

Bryce has a normal "cool" color temperature, one might guess due to the original creator, Eric Wenger, a native of Germany. Bryce atmospheres are mostly based upon cooler Northern Hemisphere climates, not ideally conducive to nice skin-tones. I have noticed that the general color temperature of VUE, a French program, is somewhat warmer in tone... Poser generally defaults to a warmer color temperature, but a somewhat lousey wide-angle lens. Most people recommend subtle warmer lighting and a 100-135 mm lense for best Poser renders. This is based upon how professional photographers work...

One thing to do is make sure all of your Poser figures use white as the Object color, so the textures set the color for the item entirely. Many of the default Poser figures use a color here that colors the texture map somewhat, Bryce treats that differently. Other than that, I haven't noticed a lot of difference, other than the default lighting in Bryce is set very bright, and the shadows are very hard.
