Quote - It appears the developer is more concerned about making Nvil a 64 bit app than in doing any kind of tutorials...

Sorry but Nvil is not very user friendly. It maybe more stable than Hex but I find Hexagon's crashes less stressful than having to navigate a messy gui. And I very much dislike the left clicking bringing up a mess of word balloons....

I think that's definitely a concern that should take presidence to tutelage.  There's almost no use for a 32bit application in this age of high resolution modelling.  Even next gen game engines are supporting polygons in the millions.  Importing zedbrush or voxel models for topology makeovers can choke a 32 bit app quickly.  Nvil is clearly aimed at seasoned modellers, looking for an alternative package to Silo, or to compliment the tools in their high end suite.  The popup navigation, and customizable keyboard shortcuts in Nvil are not for beginner modellers, but tools which, once mastered, help make workflow much faster than constantly reaching for buttons or scrolling down panels in a UI.

I understand why you might not appreciate that kind of workflow coming from a package where the UI dictates the workflow, but many advanced users appreciate the ability to totally customize the way they work to suit their style and pace.  I think this is why there is a shortage of tutorials.  The users who will gravitate toward a package like Nvil won't really need, or want them.

Personally, I'm not a fan of Nvil's UI either, because even though it's customizable, it's not appealing in the least.  Doesn't make me want to work in it for as often as I will need to on a daily basis.  My ideal modeller should look as good as it functions, because I'll need to look at it more often than I look at my girlfriend every day.  3D modelling apps are like girlfriends to me, in my line of work.

However,  I find Nvil very comprehensive in the way of tools and features.  You aren't left wishing it could do this or that, because it's got a great feature set, and that to me is what is most important of all.  It has a great heart.  If I weren't already involved with C4D, I'd definitely take it out on the town, even though I probably wouldn't show it off to my mates.
