Hi Pilou,

Very interesting indeed but ...let's take a look at the "Advanced Features" section of the official page at http://zbrushcore.com/features

It misses almost everything that it's needed to be a really good Polygonal 3D Modeler.

First of all it misses : ZModeler, Edgeloop, Crease, Automatic retopolgy...just to name a few.

Furthermore, in the "Texturing" sectiopn of that page, we can read :

3D painting capabilities (PolyPaint) : Basic,
Texture Map support : NO

Certainly it has the Zbrush heritage but...I think that it's just an heritage.

We will see...

Nice day,
