I've been using poser for a decent amount of time(since 2005) and; for fun, have ventured into other avenues like modeling(just basic stuff, I'm really not that good) texturing(getting better) and morph creation(getting better) using mostly V4. For some time, I switched to daz studio just because I couldn't get clothes to fit V4 very well. Since the PP2014 has come out I've been back using poser exclusively.

I work as a residential designer/draftsman for a decent sized architectural firm. Our workflow basically goes like this: Autocad for initial design and construction documents, Revit for basic models of our autocad designs and then production rendering usually with Revit. I'm familiar with a lot of the higher end rendering solutions for revit such as importing to 3ds and using vray(won't go to octane as we're not about to upgrade our render farm to all cuda vid cards), maxwell, and Indigo.

What I'm looking for is some insight into a decent workflow that'll take me from Revit to being able to render in poser using the reality/luxrender combo that isn't going to involve a week's worth of mesh editing and material tweaking.

I can only speak for OctaneRender for Revit (and yes, I know that's not an option for you).....in that plugin you can select a Revit family instance and assign a proxy to it.  The proxy is either an OBJ (A clothed and posed Poser figure exported as OBJ works) or a pre-packaged Octane Standalone geometry element.  Then when you render in Octane from the plugin, that OBJ proxy (the Poser human figure in this case) renders in the scene in place of the family instance.  You can then scale, rotate, move and change the materials of the proxy geometry object.  This is all done from within Revit - no need to export to another modelling or rendering app.

Going from Revit to Poser is unlikely to work - because when you export from Revit the materials are lost.  A workflow that might work is going from Revit to 3ds max (since I think 3ds max can read the Revit material libraries), then export to OBJ and import into Poser.

The other thing to consider is that unbiased renderers are typically very slow at rendering interiors (since they have to process ray bounces through glass, etc) - so you want the fastest renderer possible.
