Portrait of a silent man by Patrick Eischen
About the image
There are many rendered portraits in a lot of galleries. I was always impressed by the high quality of the MentalRay FastSkin shader and how easy it was to set it up once you understood the basic concept of how skin works. But as I 'only' have Cinema 4D, MentalRay is not an option for me. But isn't it possible to render realistic skin in Cinema 4D? I wanted to find out with this project.
Modeling
I usually start my 3d models with a simple cube (box modeling). I know that many prefer point-by-point modeling (or poly-by-poly) but I like using a cube and 'cutting' the detail in, step-by-step. Box modeling allows me to quickly block out the basic shape of the figure and thus to have a better feeling for the proportions of the model. But because I am using good references, any modeling technique would have worked.
The face finished, I began laying out the UVs (maybe the most annoying part of this job). Fortunately I found UVLayout (by Headus), a program that flattens 3D geometry automatically.
Textures
I took the model into ZBrush to add a texture to the face. Every inch of the texture comes from high-resolution photos which where projected onto the model with the ZBrush tools. Wesclei Barbosa has written a tutorial about how to do that. All my reference photos as well as the texture references are from www.3d.sk
This is how the final head texture looks:
