Hi
Did this only with curves.Remeber me Zspheres in ZBrush...I used a lot zspheres with unified skin in Zbrush, against adaptive skin , the most usual method for zspheres.Any way the mesh results in zbrush unified skin is poor compared to voxels.
With some improvements at the splines manipulation this can be a good way to create with freedom with voxels at 3DC.
But is very fun already.
