set up .rvt files for 3ds max import

[vanderloo5]

What determines what gets assigned generic materials in Revit?
When I import my .rvt model into max, (by material), there are 20 or so items that highlight when I select one beam. And they are listed as "Generic" and include door jambs, metal railings, and various other items.
But when I assign different materials to them to try to separate them,(in Revit), they still all select together in max after I re-import?
I've tried assigning different materials in the Revit properties palette and by painting objects with new materials. But I still can't select them individually in 3ds max.

I'm currently trying to form a material set in Revit that seamlessly imports into 3D studio & uses predefined Vray materials. I wanted to use AutoDesks ACBEditor, and couldn't get it to run in windows 7. So I had a look around for an alternative (no luck) and found an interesting web site that walks through the steps on import & export of FXB.
I think there is a way of importing your Revit file, to map materials correctly, from the guide, and it may help you too.
Have a look and offer some feedback, and if anyone else has gone through this process successfully, please share.

https://bim.wikispaces.com/file/view/Revit_3DS_Unity+Workflow.pdf – has a step by step method of exporting a Revit file to a valid FBX one, with a vital LOD setting, and a detailed import that include material mapping in 3D Studio (page 8-16 of 22).

Do NOT combine entities should be your selection from the pulldown. Do not choose "combine by material". I don't completely know why that's even a choice.
