Here is a render out of lightwave I did using the figure and scene I mentioned at the beginning of the post.  I made some changes and messed with the lights.  The figure I am using has a texture map, epidermal map, subdermal map, blood map, bump, spec....  The lighting in Lightwave is superior in my opinion.   With a lot more work you probably could produce similar results in Carrara.  It's a great tool (Carrara) I just hope DAZ brings it forward.
