Is it a better idea if I render my scene with various light sets to see what settings give me the metalic and shiney surfaces that I think look realistic and then take note of the settings in the material room for the metalics and shiney surfaces and make the same settings in the material room for the metalics ,shiney surfaces  for  the light set that I feel gives a realistic skin texture? Because at the moment I'm happy wiith the lighting set I made to the skin texture ,but not happy with the look of the shiney surfaces and metalics .Both of these look very dull and nothing like what they are supposed to .
