I've done this project to get familiar with the new functions of Zbrush 3.1 and to create a much more realistic head of dinosaur, and this time, with colors. Mainly inspired from Weta digital (Weta workshop) design, here are the steps for the creation of the V-rex bust.

Zsphere and retopology

I start by creating a basic mesh from Zspheres. This gives me a simple basis to create a first sketch of the general shape.

This is the mesh in subdivision 2, resulting from the Zspheres, and ready to be modelled before the topology.


New function in Zbrush 3.1: editing topology enables you to draw a new polygonal basis, easier to deal with, from the previously created model. With the Projection function, you can get a preview of the details (if you have some) of the sculpted mesh coming from the Zspheres. And you can also keep this preview then.

This is the new clean topology. It will be my basic mesh for the final sculpture.


The masks are really useful during the sculpting step: they help you creating much cleaner distortions (hard lines).
Example of the use of masks:



These are the brushes I use the most. With these brushes, I can realize all the details of my sculpture:


New tool in Zbrush 3.1: the Local tool, really useful, enables the focus on the working area on one part of the sculpted model, according to where your brush is.







Only in Zbrush 3.1: the SubTools.

Here, I manage all the parts of my sculpture (teeth, eyes, tongue), these parts have been created either in Zbrush, or in Maya and are imported one by one in my Zbrush scene.
Then, I can sculpt and paint these elements separately.

SHUT UP ... ?


Again a new function of Zbrush 3.1, with the Transpose function, you can change the position of your model, without going through the animation tools of classic software.
This function works with masks and the Move, Scale or Rotate tools. This is really important to be fastidious in the creation of your mask. The mask can be either automated (Move mode) or hand-painted in Brush mode; you can also combine these two modes.
