Yeah i noticed that lighting has a LOT to do with realism, and definitely makes the difference between a good render and bad render. I tried out a few indirect lighting sets, which were designed with a backdrop for solo characters, and it rendered really clear, like a photograph. The problem though, is that the sets are designed for studio/solo poses, and have about an average of 15 lights. Besides baggin's free set, are there other indirect lighting sets or techniques to achieve that realism, but with more versatility? Also, i noticed that diffuse IBL with HDR images tend to produce pretty good quality images. So much things to test my head is about to explode ><
