Quote - 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. 

Its interesting that ZBrush is still 32bit, AND that it can produce models with a super high polycount.

Otherwise, yes, most 32bit apps are quite limited. I would agree that the Nvil developer is smart is spending the time to get it ported to 64bits before doing any more work in other areas.

The Nvil interface is a bit of a turn off, but not so much a ZBrush or Blender. I know its possible to customize it, but if it can be reskinned as well, that would be nice.

I would definitely look at Nvil again once there a 64bit version available.
