I haven't had much free time lately to do 3D stuff on my own at home, but I really wanted to try out a new feature in ZBrush. The latest release included a tool they have been developing called "ZRemesher." It essentially uses complex algorithms to analyze the surfaces of your sculpts to create a base mesh that works with the curves. With the addition of this tool, it makes sculpting that much easier.
I did the above old man in about two hours in ZBrush. It started off as a Dynamesh sphere where I got it to the proper size. After that, I drew some curves on the surface to suggest how the polygon flow should be generated, then let ZRemesher do its magic. I can't complain:
This truly solidifies ZBrush in my mind as a great development tool. It's great to worry about technical details later and just focus on the creative at first.
