Aside from ZBrush, Hexagon is the only one that's integrated with DAZ Studio that way.
The bridges are currently only content export projects, I
would imagine that they receive a similar two-way integration over time.
You can however use Morph Loader for manual importing as morphs, that way you can use any 3D modelling application. It's not as quick as a one-click round-trip, but it gets the
job done.
