I am only using Revit 2012 so it looks like I will just bring it into 3D max Design 2012 that I also have and redo the UV mapping. Not a big deal, thanks for reply now I know and knowing is half the battle! GO JOE
Sounds good Billy. Knowing that you're using a Revit/3ds Max workflow (same for me), I can offer an extended workflow suggestion. An easy tip for your roof in 3ds Max is to:
1. Apply a "Mesh Select" modifier to the roof.
2. Select the faces where the roof panels are going the wrong direction.
3. Apply a "UVW Map" modifier to the selected faces and orient to the correct direction.
The above approach works very well using Max's file-linking for the Revit file (using FBX). So far I like using file-linking Revit models into Max. Lumion handles FBX imports in the same way. The result is that you can pass an FBX model from Revit to Max and from Max to Lumion while maintaining the ability to make edits in Revit. So, even in the 11th hour, you can:
1. In Revit: Make a last minute update to the Revit model.
2. In Revit: Export/overwrite the FBX used for 3ds Max file-linking.
3. In 3ds Max: Update the file-linking (reloads the Revit FBX file).
4. In 3ds Max: Export/overwrite the FBX file used for Lumion (I make this a different file than the FBX from Revit).
5. In Lumion's Edit Materials mode: Hit the update model button to reload the FBX file.
It's slightly convoluted, since you're passing the Revit model through Max, but being able to make last minute edits in Revit is a huge plus. I recently worked on a project where the Revit file was changed on the last day. My coworkers were apologizing for the last minute change fearing it was a hardship to me, but it wasn't! I was able to reload a fully updated model into Lumion within a few minutes.
That's more than you needed/wanted, but hopefully it helps.
