“In these 3 video tutorials you will learn how to create a vase using ZBrush. Will use the radial symmetry to construct the overall shape, use the mesh extraction to cut the hole on the top and finally use the ZProject brush to project the character face on the body of the vase. These tutorials created by the Pixologic (makers of ZBrush) for the 3D community, so everyone can easily go at advanced level in ZBrush and extract the full potential of the ZBrush. As always you can also download the files in flv format for later viewing.”
