I am trying to import a model to Lumion from Revit. This is the Workflow: Revit 2012( FBX) to 3d Max 2012 (FBX) to Lumion. As we all know, with this workflow the materials are lost during the process and you end up in Lumion with a white model w/o any materials. So I need to reapply all the materials in Lumion...... but I am having problems selecting the different components of my model.. the model is imported to Lumion  with several grouped components and can not apply a material to an individual component. ..( example if I only want to apply a material to the mullions in the curtain wall only, i can't because it applies the material to all the selected components (beams, foundation , overhang,railings, etc) (SEE IMAGES). Does anyone experiencing this problem? Any ideas on how to solve this problem?

By the way it is impossible to select the roof and the chimney in this model |:(

I try to open a collada DAE file from max 2012 to Lumion, but the file crashes Lumion, do not know why?
(I am attaching the DAE and FBX files that i used for this model if someone wants to take a look)

Thanks!!

Lumion also crashed on my pc with the .dae example provided.
I could however import it into Max.
Have a go at the attached file, see if it's better.
It's Open Collada, exported with Max2011 and it does import into Lumion.

As for the chimney and the roof:
There is a multi material assigned to them which makes for triple or more material ID's per component.
You need to clean this up.
Make sure every component that needs a seperate texture, has a unique material ID.
Should take care of the remaining issues.
Good luck!

Lumion crashes upon import of an "Autodesk Collada," and as an "Open Collada" exporter is not yet available for Max 2012 we are left waiting.  I think the problem with FBX from Revit comes when you modify a material in Revit and then import that shared material, which is pre-modified in Max.  Max then assigns a double identifier for that material upon export as an FBX, making selection impossible.  All of that is compounded by the Mental Ray materials used by Autodesk.

Have you tried assigning a standard material in max?  In the file link manager, select the option to combine entities by Revit material.  That should make reassignment of materials easier. 

Tip: For Revit -> Max -> OpenCollada users, select the option "do not combine entities." The files load faster and OpenCollada does the rest.

We'll take a look at the crash and see if we can fix it.

@Aaron :
the DAE file you attached works a lot better than the fbx. I do not work at all in 3d max, I just used to transfer my revit file to Lumion so I am a little clueless with 3d max interface. Did you just save the fbx or collada file that I attached and save it as collada in 3d max 2011? So you think that it is better to use collada than fbx?
Are there different files for collada dae :  "Autodesk Collada," and  "Open Collada"????

Revit uses different materials or layer in certain components i.e : roofs have different layers with assign materials, so in order to eliminate that multi materials do i have to change my model in Revit, is there a way to change it easy and fast in 3d max? in the new collada file that you made I was able to select the roof, did you modify it or It was the 2011 collada file that was not interfering with Lumion?

Thank you for your help and patience, since I am a new bee in the 3d max world. But all the sugestions are really helpful. I wish one day i can import my models with all my materials assign, it will be perfect!!

Hi Jordan, please check your hotmail account - I contacted you about the Revit -> Lumion conversion procedure last Friday :)

(The crashing DAE file has been forwarded to our import/export guru, Artur)

We've found quite good solution which will make possible to importing from Autodesk collada  into Lumion with perverse materials. It will probably be included in next build. I'll put the screenshots here soon.

@Morten: hi Morten, yes I received your email and I also respond to it. Did you receive my files? I sent the fbx files you requested: one with a box with brick material and the other one with plastic material. They were made with REVIT 2012 and were saved directly from Revit as an FBX . Let me know if you got them.

@Arthur: That sounds great............. That will save us a lot of time...... Are you going to include this in this new build... "BUILD 3" that is coming this week? Can you tell me the workflow? Can I use it with REVIT 2012 - 3dmax 2012 -Lumion? . Did you get the crashing DAE file created in 3d max 2012?

Thank you guys for your help and for this amazing software!!!

Hi Jordan,

Your workflow will work. (Revit 2012 -> Max 2012 -> Lumion)

- DAE not crashes now
- you can select separated components
- Roof is selectable

It will be included in build 3

Does it maintains the original Revit materials or do I still need to apply them in Lumion?

Looks like you have to reapply based on the black pieces in the above images.

Arthur:
Just to let you know the Autodesk FBX exporters does not work, only Autodesk Collada. I found a couple of bugs when I import some files with Autodesk Collada.(see image attached) :
I was unable to apply materials to the window and door frame and the glass does not get the transparency. Overall is working ok with the different components, except doors and windows.

Thanks!!

Have you tried Revit->Lumion as FBX from Revit?
