I know this may be a long term request, but I would really like to have an Enscape plugin for Navisworks (now that you've tackled Revit, SketchUp, Archicad, and Rhino).
We've been getting a lot of mileage out of the Revit plugin, but are running into more and more requests for VR of the entire coordination model, and having a Navisworks plugin would make life a lot easier for us! Plus, it's also a less crowded space when it comes to VR/real-time rendering plugins as opposed to Revit, could be a good time to establish your corner on the market...
