Error with Testingscene

Hi

I'm using the new Official Release of Blender 2.62 and the Exportscript 3.2.12.0.
I'm using the Testversion of Indigo RT.

I have the Error: Error: [Indigo 2012-May-10 07:50:45] 'NoneType' object has no attribute 'indigo_material'

It's a Scene which I was using for testing Cycles.
When I assign the same material the all Objects then it works.
When I delelete the Plane-Object which as no Material actually, then Blender crashes while exporting the Scene.

Here is the Scene: http://www.archiviz.ch/download/Kueche_ ... packed.zip

Does anybody know what I do wrong ?

Kind regards
Alain

Your object "mesh108" had a material slot but no material assigned to it.
The emitting mesh for the Carpet particles also had no material assigned to it.

It will help you a lot if you assign meaningful names to your objects and meshes. I am not sure why the error message did not properly identify the object (mesh108) or mesh (Kuech_11_21012012_g_36732-Fen_Leibung_innen.003) it had a problem with.

I fixed that and it rendered.

I'd strongly suggest you place exit portals over all the openings, otherwise the render will take forever

Thanks for your help !

How did you find out that mesh108 had no material assigned to it ?
Did you check each Object by hand ?

I made the Model in Sketchup, thats why Objects are not named properly.

Exitportals are still not supported by Pathtracing GPU-Mode, right ?

Kind regards
Alain

Yes. I hand selected them to find the one without the material.

You are correct. Simple path tracing still does not support Exit Portals. It will render an image but you will not see the directly lit sun patches.

However, for interior renders that are illuminated by exterior light entering through windows, simple path tracing is generally not the best render mode. Bidirectional Pathracing works much better in these cases, alas is not GPU supported.

If you ever decide to turn on the little overhead lights in the kitchen cabinet you may even want to choose Bidirectional + MLT. Then you add a few glass objects, perhaps a table with a glass plate or a little glass sculpture and you definitely want to try Bidirectional + MLT.

In each case compare the render with cycles
