I really don't want to stray from the topic but I have to ask you to elaborate a bit on that. I'm doing my last year masters's of architecture degree at the moment and to be honest I'm stuck with Rhino+gh for heavyweight modelling (acad and revit are part of my workflow as well). I almost always export my models to max for rendering because I'm not happy with the Vray implementation in Rhino.
Generally, I'm doing simple exteriors with Rhino+vray, complex exteriors with a lot of vegetation with exported rhino model to Max+Vray and interiors with exported rhino models in max. I completely realize that this is quite non-optimal. I'm eager to learn max modelling but after modelling for 5 years with rhino+gh it is hard to see the benefits.
And don't get me wrong I'm not trying to be lazy, part of my current skills is processing, python, rhinoscript, I don't mind looking more closely at max modelling. The thing is that for me, Rhino modelling makes sense and is more logical.
If my rhino models increase render time in max (something that I have not noticed) ,this changes everything.
