I decided to install the Learning edition of Silo to see what all the hype is. As a partner for zbrush, based on 1st impressions, Wings3D beats Silo. Of course this is just an opinion, but i’ll explain also. (keep in mind the below is based on first impressions, and I know enough other apps, to know what’s hot)
I’ll start with what I like about Silo. the customization is great. Probably it’s greatest feature. Iso-lines are awesome in any package, including this one.
now Wings. Selection is the best feature of all in Wings. you get named selection sets, and switching selection types converts your last to current. (selected edges, converts to face sectlection or other) Even edge loops are cooler, you can goto the next loop, and back. other selections types can grow and shrink. soft selections (refered to as magnets) have options to determine what shape soft selection takes, and is easier to control.
other things I like, camera can be instantly moved around without keyboard combos. The face lift feature and Tweak mode (unrestricted, quick editing) are totally cool. plenty of tools for vertex manipulation, including bevel, normal movement, and deformations. Texture mapping can be automatic, or done just like 3d copy in zbrush. The UV editor can break up your model as you like, just like costly UV mappers.
Overall first impressions of both software is very good, for thier cost. Silo is more like a full solution to 3d. Wings is more of a partner to other apps. It does anything you need for polygons. The direction Wings is headed, iso lines are around the corner, which will make the difference even less. If you are familar with modeling already and have other tools, Wings is the best choice. It’s easier to work with, and just so fast. If you have no other tools, Silo would be better. It way more complete, but doesn’t realy offer much that the more costly apps don’t have. Wings is not a complete package, but offers so many polygonal features, that I was shocked that this thing is free, cross-platform, and open source.
for Zbrush, I’d have to go with Wings. currently you can preview or render higher sub-d levels, and offers UV mapping features that zbrush doesn’t have. Zbrush needs a partner that can create simple polygons, and custom UV mapping. Wings delivers this perfectly.
