Physically Based Rendering[0] is big these days. Materials can be acquired using special scanners[1]. The result is that you can have a library of materials that behave in predictable ways in a wide variety of situations. Artists still have a lot of freedom, they can chose materials and change lighting, just like in a real photo shoot.
