When i export a FBX file from Revit (2011) to Lumion there are no textures, but only a white model.
If i import the same Revit-FBX into max i have textures. (export
Revit -> max -> Lumion is not the best way and generates errors by
exporting FBX, max craches)
As far as I know, the problem stems from the fact that Revit uses MentalRay materials and when you import a Revit FBX file in 3DS Max the materials are preserved as MentalRay materials.
Unfortunately, the FBX and Collada exporters in 3DS Max have no clue what to do with other material types such as those used by Vray/MentalRay, so that's why you simply get a white model in Lumion.
For that reason, my suggestion to you, Jan-Willem, is to try to convert the MentalRay materials to Standard materials in 3DS Max, and then export the model to .DAE with the OpenCollada exporter. I'm not 100% sure what the most effective MaxScript for material conversion is, but there's a few free ones you could try out on ScriptSpot etc. jordan230 said:
I am experiencing the same issue. I just read in the forum that the only way to export Revit fbx files to Lumion is via 3d max. http://lumion3d.com/forum/gene.....bx-issues/
Again, the problem is that Revit is using MentalRay materials, and only the custom-made FBX importer in 3DS Max knows how to interpret those material types. That being said, you can in fact import your Revit model without 3DS Max – as long as you don't mind re-applying textures/materials in Lumion.
Download and install AutoDesk's free FBX converter2)
Convert the Revit FBX file to FBX 2010 or 20113)
Import the FBX file in Lumion (It's white but better than nothing I guess)4)
Apply Lumion materials to the model and manually add the correct textures/UV scale
I realise that this isn't a workable solution in the long run due to the extra work involved in applying materials, but I just thought I'd let you know that there is a way to import your Revit model without 3DS Max…
