I'm rummaging through old work that has outlived it's NDA ;D This is a frame where I was experimenting with materials, lighting and mood. A cool experiment I found here was a "curvature pass." A curvature pass is a render element in Vray. If you look in the cracks between the lips and also the eyes you'll see the color turns brown. The brown comes from the curvature pass. It's similar to an ambient occlusion pass except it's sharper and really finds any area that has a recess. It's a great way to add an extra layer of depth to a material like marble.
