FBX Import loose textures

Hello,

 

When i export a FBX file from 3ds Max (2011) to Lumion the texture come in with it.

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)

 

What is happend by importing Revit FBX into Lumion?Cry  (the model is allright)

Unfortunetly Revit saves some FBX materials in special way which only 3D Studio Max can read. Currently Autodesk doesn't provide any way to support it in Lumion.

 

If 3D Studio Max crash when exporting your file to FBX, try to export it to DAE (via OpenCollada exporter).

So workflow is Revit -> 3D Studio Max -> (DAE) -> Lumion.

@ Jan-Willem:

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/

 

I work with architects that only use Revit for 3d modelling, renderins and Construction Documentation, they do not use 3d max. This is not good since you have to use an extra software (like 3d max) in order to use Revit models in Lumion.

@ Lumion Staff

I was wondering if Lumion staff is resolving this issue, since most of the Architectural firms right now are doing the transition from Autocad to Revit, and in order to use Revit files into Lumion, these companies may have to purchase 3d max in order to use revit files into Lumion (and I don't think that would be practical, affordable and a good selling point). I think this issue has to be resolve ASAP since this software( Lumion) is target to Architects ( we need  easy and fast workflows-there is no need to use extra software or re-apply textures). 

Other than that I think this software is amazing. Keep up with the good work!!!! But fix FBX export for Revit into Lumion, is a MUST if you want to sell and target Architects as well as the architectural visualization community.

You understand that if we could fix this quickly it is our top priority. But as Artur states apparently it saves FBX in such a way that only 3d studio max can understand it. Saving special xm files etc.

 

But we will try to keep looking for solutions for this problem since you understand that it will greatly help all people that will want to go from revit to Lumion. And it is our goal to make sure that from all architectual software to Lumion 3ds max is NOT needed!

 

Let's hope we succeed creating a special workaround for this weird method of saving fbx from revit. Let's hope they add DAE support as export format that would also solve the problems.

Maybe a .dae plug-in for Revit.  Does such a thing exist?

Thanx for quick response guys Laugh

 

Artur: i was thinking tonight about that and i now DAE export is a way to try.

Now i now that is at this moment the only way.

That was the question, thanx!

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.

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.

Here's how:

1) Download and install AutoDesk's free FBX converter

2) Convert the Revit FBX file to FBX 2010 or 2011

3) 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…
