Hi Raven, you can make portraits of individuals using Seamless. How much of a likeness you can attain will mostly depend on your artistic skills, much the same as if you were trying to capture a likeness using a pencil or paintbrush.
Although it is pretty straightforward to model a face and be able to spend time practicing to develop your skills using my up to date tutorials (Witten for Seamless3d 3.000 and up), to do tasks not yet covered in my tutorials such as making hair, importing objects, painting and animating, it wont be so easy. There are a number of loose ends I want to first resolve in Seamless’s interface as well as fixing a few bugs, before I make any new tutorials. How long this will take is impossible to predict but I am hoping by the end of this year 2015 I might be able to start showing how to make a complete animated movie using Seamless3d 3.
