ChaseCamera but static light - possible?

Troubleshooting graphics
1

Hey all,

I am a JME noob trying to find an easy solution to using the ChaseCamera to orbit around my main model.

Is there an easy way to avoid that the camera also "orbits/moves" the light source in the process ?

My current thoughts:

Either move the light source in the opposite direction of the camera movement, - or

Use more than one camera ?



Any help appreciated !



Cheers

I don't think the lights should be moving with your camera. How is your scene setup? Are you using any light nodes?

Hi Rimon,

I dont use Lightnode but a pointlight attached to lightstate and it seems to move the lightsource as well (the shadow is always in the same place !):

    protected void simpleInitGame() {

        pl = new PointLight();

        pl.setAmbient(new ColorRGBA(0.75f, 0.75f, 0.75f, 1));

        pl.setDiffuse(new ColorRGBA(1, 1, 1, 1));

        pl.setLocation(new Vector3f(10, 0, 0));

        pl.setEnabled(true);

     

        lightState.attach(pl);

       

        ObjToJmeNew converter=new ObjToJmeNew();

        try {

            URL objFile= this.getClass().getClassLoader().getResource("my/pack/c-ds2.obj");

   

            ByteArrayOutputStream BO=new ByteArrayOutputStream();

            converter.setProperty("mtllib",objFile);

            converter.convert(objFile.openStream(),BO);

           

            Node r= (Node)BinaryImporter.getInstance().load(new ByteArrayInputStream(BO.toByteArray()));

            rootNode.attachChild®;

            Node cir = (Node)r.getChild("Cir");

            Node cube = (Node)r.getChild("Case");

            Spatial empty = r.getChild("MyEmpty");



            Texture tex = TextureManager.loadTexture(this.getClass().getClassLoader().getResource("my/pack/chrome.jpg"),

                    Texture.MinificationFilter.Trilinear,

                    Texture.MagnificationFilter.Bilinear);

            tex.setEnvironmentalMapMode(Texture.EnvironmentalMapMode.ReflectionMap);

            TextureState ts = display.getRenderer().createTextureState();

            ts.setTexture(tex, 1);

            ts.setEnabled(true);

            MaterialState ms = (MaterialState)cir.getChild(0).getRenderState(RenderState.RS_MATERIAL);

     

            for (int i = 0; i<r.getQuantity();i++) {

                Node firstchild =  (Node)r.getChild(i);

                if (firstchild.getQuantity()>0)

                    if (firstchild.getChild(0).getRenderState(RenderState.RS_MATERIAL)==ms )

                              firstchild.getChild(0).setRenderState(ts);

            }

     

            chaser = new ChaseCamera(cam, r);

            chaser.getMouseLook().setLookMouseButton(0);

            MouseInput.get().setCursorVisible(true);

            System.out.println("CRASH");
