When exporting to FBX, the materials don't work anymore. What happens now is that everything exports as one generic material. This worked fine in 2010, but doesn't work in 2011.
PLEASE FIX THIS ASAP ! ! ! !
It is hugely inconvenient and time-consuming to have to export a model material by material. It's playing havoc with my deadlines. Please respond and let us know when we can expect Autodesk to correct this problem.
You may be having problems with different versions of software. the materials being transfered in revit 2011 to Max 2011 are new material types, that might be causing you these problems.
If you create a new model in revit 2011, export to max2011 the materials will come across.
Additionally I would reference the following post as there were numerous updates for 3DS Max which addressed some FBX material issues:
