I know most of you "In the know" will roll your eyes, as I did.
However, it appears that Nevercenter is finally updating Silo 3D.
Evidence is on their Facebook and CGTalk Forum pages - just FYI.
I won't fault anyone's skepticism after waiting years myself but, this is good news IMHO.
I'm excited because, I've found very few programs that are as intuitive and fun as Silo.
Although not perfect, Silo 3D was truly zen and allowed me to feel like an artist when modeling.
Plus, Silo + 3D Coat Merge Tool = A Whole Lot of Fun!
Regarding Inuitive Programs:
Here's my "favorites" list of amazingly well thought out and intuitive programs that stand apart IMHO:
3D-Coat (of course which is why I'm here + just about the best devs and community ever - pardon my fanboy gushing but so many of you have made vids/tutorials etc along with great code + the Photoshop and tablet friendly design is genius. I can't tell you how much I appreciate the little things like customization and menus opening where I'm working instead of me going to them. It's just brilliant.)
Mudbox - use it and you'll just know why - simplicity and focus.
Sketchbook Pro - Best drawing app (I'm also using Manga Studio 5ex - powerful, but, sketchbook is just so simple an friendly.)
Please add your own as I'm always interested in finding tools that bring happiness to my work.
