Here’s some photo refs I almost used (and maybe I will someday) of Gwen Stefani’s face. She has a gorgeous face I nearly used on a mesh.
Feel free to use this if you wish. Place this in the background of your front and side 3d views. It’s better to follow the form of an image than to work from nothing.
This can be done with any front and side views of a person. The straighter the views, the better the results.
I found a good straight on pic and side profile, and using photo manipulation software (Gimp, but you can use photoshop or whatever) line as many of the features up as posilble. Use guidelines.
First I made sure her face in the front view was straight. I rotated her head about 5 degrees so the verticle line ran down the center of her forehead, nose, lips, and chin. Then I drag horizontal guide lines to help align her features in the side view. Rotate the side view until as many features line up with the guides as possible.
This side by side of Gwen is pretty good. If I were to actually build this I’d need to fudge a few things. Her mouth is relaxed in one view, and in a half smile in the other. Her eyes have different expressions. I couldn’t get the ears to line up, so I would pick a happy medium.
Theoretically, yes. You can recycle good topography as much as you want. The meshes that were done for Final Fantasy all were done with the same topography, simply re-shaped.
