Collada, Max 8.0 export


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.

        //If we want to display the skeleton use the BoneDebugger.
        if(boneOn) {
            BoneDebugger.drawBones(rootNode, display.getRenderer(), true);

    protected void simpleInitGame() {
        KeyBindingManager.getKeyBindingManager().set( "bones", KeyInput.KEY_SPACE );
        //Our model is Z up so orient the camera properly.
        cam.setAxes(new Vector3f(-1,0,0), new Vector3f(0,0,1), new Vector3f(0,1,0));
        cam.setLocation(new Vector3f(0,-100,20));
        input = new FirstPersonHandler( cam, 80,
                1 );
        //this stream points to the model itself.
         InputStream mobboss = TestColladaLoading.class.getClassLoader()

        //this stream points to the animation file. Note: You don't necessarily
        //have to split animations out into seperate files, this just helps.
        //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.
        //attach the skeleton and the skin to the rootnode. Skeletons could possibly
        //be used to update multiple skins, so they are seperate objects.
        rootNode.updateGeometricState(0, true);
        //all done clean up.
        PointLight pl = new PointLight();
        pl.setAmbient(new ColorRGBA(0.5f,0.5f,0.5f,1));
        pl.setDiffuse(new ColorRGBA(1,1,1,1));
        pl.setLocation(new Vector3f(10,-50,20));

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) {

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

I uploaded the quader.dae here:, 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
