I did a test run on projection mapping in zbrush for the Britt bust texture using a junk lowpoly version of the sculpt. The texture is generated from several views of her face. I threw on quickie UVs to test the face which is why there is stretching on her shoulders. I really really like projection mapping and how well Zbrush works with Photoshop in this regard.
Top is best render with perspective. Left is BPR render, and right is Best Render with the mesh and perspective turned on. I don't have eyes in yet so her eye texture is just projected into the socket.
