well I vote for the Cyclorama . This is a render i am working on for the Cyclorama useing a back ground photo i took at the beach with global lighting from daz. I think most people do not set it up right and with out shadows cast it will make the plastic look . P5 has its own settings that make it look good but i use p4 so i do not know what they are. Some times its a matter of droping the cyclo to the floor as well as making sure that cast shadows is unchecked for the cyclo but NOT the other items in the scene. The cyclo did not come with any pre set lights . I look forward to seeing your product nacey.
