I hope it’s ok to post a challenge? Especially since i’m not skilled enough to participate!!.
As a VERY new user to zbrush, I have parused these forums in awe and wonder of the superb artwork by so many talented people. It is clear to me that organic modeling, in particular, is very well suited to this program. I have seen some models with “sharp” and defined edges and I thought it would be interesting to see, using zspheres as a start, to create Non organic objects. Mechanical, archetecture (basic) even bio-mechanical. (my personal favorite, yes it’s somewhat organic but you get the idea)
