I produced a series of videos for people that need help making a Biped out of Zspheres. It shows you how to use shapes rather than mash allot of material on a mesh using the Zadd Zsub. Also touches base on modeling from a reference and making multi sub objects out of Zspheres.
Only Zbrush was used. No external programs;)
Reference does not count lol.
Hopefully it helps. It was probably the most Challenging Video I made. Because of the problems with the rig, at first. If you don’t have a good rig your sculpt will not survive The pose!!!
