Again, thanks you all for your kind words
@Sergiolov : Thanks you. I don't think I will have time to make a big enough tutorial that would justify costing money. Instead, I will try to occasionally add quick tips of some hidden features I found out that was useful
@NickZ : Thanks you Nick. I'm not sure I understand well what you just said, sorry for my bad english. Actually, the video was accelerated 2 times so it may not be obvious, but I applied an adaptative skin on those zsphere to be able to transform it into a dynamesh. But the adaptive skin, with the ZSpheres 2 since ZBrush 4, works so much better, and give you a much excepted result. Maybe that's why the mesh looks like the zsphere chain. Or maybe I didn't get what you exposed and I would be sorry.
@hawktime2010 : Hi Talonhawk, glad to see you there and thanks for your support
