Looking great - I can’t wait to try this.
I used to use unified skinning a long time ago in ZB2 and before but sort of let the technique fade. I think the last time I used it in ZB3.1 the poles did not sculpt well at all so I let it be. If I recall correctly, unified skins were not generally symmetrical, so hopefully these will be. And the zsphere skeleton looks like a development of the rigging feature they showed in some of the very early pre-ZB3 tech videos. Either Pixologic are very good at adapting old tools to new uses or they have a long-term development plan.
I think the first button is ‘Armature’ and I’m guessing from the on-screen action that the buttons just right of centre are for display modes (like the X-ray mode) but the rest are too hard to see, though they have some funky icons.
And if we are putting down a wishlist, I’d love to be able to close zsphere loops off to get rings and such like
