C un pen 3d ça Pilou.
It’s a blast. I first got to try it about 5 years ago when it was fairly new, and then 2 years later I actually got to use it in production for a couple months. That was awhile ago, before they had decent surfacing tools, and I had to learn/use Paraform, heck Maya for that matter. Every so often I bounce over there to see if my buddy has some new work up on the site. ZP is one heck of a sculptor.
