Collada, Max 8.0 export

Troubleshooting graphics
1

Hi,



I exported a simple Quader which i konverted in a mesh. Then I modified the TestColladaLoading class

that they can load my dae File. But it didnt work, I always get:



09.12.2007 23:55:24 com.jmex.model.collada.ColladaImporter load

WARNING: Unable to load Collada file.

java.lang.IllegalArgumentException: InputStream cannot be null



The file is in the right directory.



I use ColladaMax 3.03 and Max 8.0. The unmodified TestColladaLoading class works perfect.



Also, I cant load the man.dae in Max I get the error: "[6376] Mesh has source with an unknown id"

and three other warnings.



I dont know what to do, to export a simple object from max and use it in jme :/.



Thanks for any help and sorry for my bad english :).

You should post the code where you create the InputStream from a path URL or String… There seem to be a problem with the opening of the file which has nothing to do with jME.



Also, sometimes exporters/importers don't work as well as expected.

        //tell the importer to load the mob boss
        ColladaImporter.load(mobboss, "model");

        //we can then retrieve the skin from the importer as well as the skeleton
        SkinNode sn = ColladaImporter.getSkinNode(ColladaImporter.getSkinNodeNames().get(0));
        //clean up the importer as we are about to use it again.
        ColladaImporter.cleanUp();
       
     
        //attach the skeleton and the skin to the rootnode. Skeletons could possibly
        //be used to update multiple skins, so they are seperate objects.

        pl.setLocation(new Vector3f(10,-50,20));
        pl.setEnabled(true);
        lightState.attach(pl);
    }
}



I copied the quader.dae in "workspacejmesrcjmetestdatamodelcollada".

And I get a WARNING:
10.12.2007 00:41:16 com.jmex.model.collada.ExtraPluginManager processExtra
WARNUNG: Could not process extra of type: FCOLLADA

That comes not when i load men.dae.

Seems that you have the same problem as in this other thread:

I use the complete jme, no jars. I have added it in my Projekt under Java Build Path -> Projects -> jme.

Is that a problem?



When I use:


        try {
           InputStream mobboss = new BufferedInputStream( new FileInputStream("quader.dae") );
           ColladaImporter.load(mobboss, "model");
        } catch( FileNotFoundException fnfe) {
        fnfe.printStackTrace();
        }


And copy the quader.dae and man.dae in my projekt path, the "man" works, an the "quader" not.


Edit:
I uploaded the quader.dae here: http://www.htw-dresden.de/~s52377/files/quader.DAE, can someone
test it with this file?

And as I say previously, I get an warning when I open the quader.dae:
10.12.2007 00:41:16 com.jmex.model.collada.ExtraPluginManager processExtra
WARNUNG: Could not process extra of type: FCOLLADA
