    Hello,
    sorry for my english :P

    Also, i have a problem with my spatials, spaceship, earth and asteroids are transparency ???
    I have loadet and convert all the objects with MaxToJme() and load textures with ResourceLocatorTool.

    In Java2-Forum one says i need to set all models to “opaque bucket”
    i have done: “mySpatial.setRenderQueueMode(Renderer.QUEUE_OPAQUE);” but this nothing change.

    Here youtube-video to see what i mean: Video

    MyLoader:

    private void load3DSModel(){
        URL modelURL;
        FormatConverter converter;
        ByteArrayOutputStream outStream;
        InputStream inputStream;
        SimpleResourceLocator location;

        System.out.println("Lade Model " +this.modelPath +this.modelName);

        modelURL = getClass().getResource(this.modelPath +this.modelName);
        converter = new MaxToJme();
        outStream = new ByteArrayOutputStream();

        try{
            location = new SimpleResourceLocator(getClass().getResource(this.texturePath));
            ResourceLocatorTool.addResourceLocator(ResourceLocatorTool.TYPE_TEXTURE, location);
            inputStream = modelURL.openStream();
            converter.convert(inputStream, outStream);
            inputStream.close();
            this.objNode = (Node)BinaryImporter.getInstance().load(new ByteArrayInputStream(outStream.toByteArray()));

            System.out.println("Model " +this.modelPath +this.modelName +" erfolgreich geladen");
        }catch (Exception e){
            System.err.println("Exception @ load3DSModel() in MyObjects!");
            System.err.println(e);
        }
    }

    MyDefaultRenderer:

    public static void setDefaultRenderer(DisplaySystem _display, Node _object, CullState.Face _face){
        CullState cs = _display.getRenderer().createCullState();
        cs.setEnabled(true);
        cs.setCullFace(_face);
        _object.setRenderState(cs);
        _object.updateRenderState();
    }

    StarshipExtractor: // i extract all other objects at same way

    this.starship = super.objNode.getChild("Starship");
        super.objNode.detachChildNamed("Starship");
        this.starship.setRenderQueueMode(Renderer.QUEUE_OPAQUE);
        setDefaultRenderer(this.display, this.starship, CullState.Face.Front);
        super.objNode.attachChild(this.starship);

    MyLight:

    Light light = new PointLight();
        light.setDiffuse(ColorRGBA.white);
        light.setAmbient(ColorRGBA.white);
        light.setEnabled(true);

        /** Attach the light to a lightState and the lightState to rootNode. */
        LightState lightState = display.getRenderer().createLightState();
        lightState.detachAll();
        lightState.setEnabled(true);
        lightState.attach(light);
        this.rootNode.setRenderState(lightState);

    Also, anyone see what make me wrong??

    Are you calling updateRenderState() after setting up your lighting and model?

    from the video, it looks like you miss a ZBufferstate

    @ sbook
    have setting up “updateRenderState() ” but this was´t

    @ Core-Dump
    thx, this was, have setting up the ZBuffer

    private void setupZBuffer(){
        ZBufferState buf = this.display.getRenderer().createZBufferState();
        buf.setEnabled(true);
        buf.setFunction(ZBufferState.TestFunction.LessThanOrEqualTo);
        this.rootNode.setRenderState(buf);
        this.rootNode.setLightCombineMode(LightCombineMode.CombineFirst);
    }

    the problem was corrected at the planet, asteroids and spacestation but this problem to be existing by Starship.
    show new youtubevideo to see the problem: Video

    thx for help and sorry for bad english xD

    like sbook said, make sure to call rootNode.updateRenderState() after setting a render state, and also after adding anything to the scene.
    you can also take a look at the stardust code to see how i did set up things.
