Yeah Zbrush is amazing indeed.

But it would need a feature , to add volume or polygons any time of the process : like 3D Coat Voxels really that brings you total freedom.

Example :
I started A Zbrush monster, and didn't put enought volume on hands when going in sculpting details, fingers where missing.
Impossible to go back and add details/volume to the hands.

With 3D Coad, at any time you can add volume, it's like you could add Zspheres of Zbrush at any time if we could say.

Well just a feature that could make Zbrush even better
