If this helps Octane Standalone plays very well with FBX export, it's so straight forward. Sure you will need to build your materials from scratch or use their LiveDB to find some good starting points like in any new renderer.
What we do in class is look development and scene visualization for VFX, we don't use VW for technical architecture but for quick architectural design drafting when creating scenes and that's something VW excels at unlike Archicad/Revit and even your usual suspects such as C4D/3Dmax. Our workflow relies on rendering somewhere else instead of Renderworks so we pretty much got it where we need it, we don't bother with renderworks textures we just apply solid fills for better ID purposes. If you happen to have C4D then export is straight forward and you can do whatever you want with it but we don't use that for one reason or the other. So far we had huge success with Octane Standalone for both exterior and interior and with Keyshot in interior scenes. Keyshot has a nice feature of updating the geometry when reimporting the FBX/3DS from VW which gives you a leeway to go back to VW and make some changes while retaining material information. We even had a great deal of success with Clarisse when it comes to scattering the VW model all over the place for nice cityscape wide shots.
