I cannot see my sky

Troubleshooting General Help
1

I know, I am just a beginner.

But I finally got the terrain to load up with the Material. But the sky no matter what I do, does not show up.

Even when I try to load the sky as a separate scene, like in the code bellow, it still does not work.

package mygame.MyScenes;

import com.jme3.app.SimpleApplication;
import com.jme3.material.Material;
import com.jme3.scene.Spatial;

public class MyTerrainScene extends SimpleApplication {

    public static void main(String[] args){
        MyTerrainScene app = new MyTerrainScene();
        app.start();
    }

    RtsCam myCam;

    @Override
    public void simpleInitApp() {
        
        flyCam.setEnabled(false);

        Spatial mySky = assetManager.loadModel("Scenes/mySky.j3o");
        
        Material mySkyMats = new Material(assetManager, "Common/MatDefs/Misc/Sky.j3md");
        
        mySky.setMaterial(mySkyMats);

        Spatial myTerrain = assetManager.loadModel("Scenes/myTerrainScene.j3o");

        Material myTerrainMats = new Material(assetManager, "Common/MatDefs/Misc/ColoredTextured.j3md");

        myTerrainMats.setTexture("ColorMap", assetManager.loadTexture("Textures/dirt.jpg"));

        myTerrain.setMaterial(myTerrainMats);

        myCam = new RtsCam(RtsCam.UpVector.Y_UP);

        //myCam.setDistance();
        
        stateManager.attach(myCam);

        rootNode.attachChild(mySky);
        rootNode.attachChild(myTerrain);

    }
    
    @Override
    public void simpleUpdate(float tpf){

        myCam.update(tpf);

    }

}

Strangely, if I leave out the lines of creating the material and loading the texture for the myTerrain scene, the sky shows up. But when I add those two lines the sky does not…so whats up with this?

http://wiki.jmonkeyengine.org/doku.php/jme3:advanced:sky

rootNode.attachChild(SkyFactory.createSky(
assetManager, “Textures/Sky/Bright/BrightSky.dds”, iscubemapforthisonefalse));

You do not have queubucket, so it is not rendered as last, and cullhint. Just use as descriped above.

Please follow all tutorials

I did exactly as you said, and as the above tutorial you provide said, and still I got an Exception.

Jan 29, 2015 6:20:25 AM com.jme3.app.Application handleError

I don’t know what you make of this, but it didn’t work.

Let me ask you, where you fill in your asset library with the files that it needs…for instance the Exception I just pasted states, AssetNotFoundException…that’s because I might not have the required file.

Where do I get it, and how do I place it where it needs to be?

The asset “Textures/Sky/Bright/BrightSky.dds” is in jme-testdata.jar like every asset used in Test, tutorial,…

You can add the library to your project (~50Mb) or extract only the required files and place it under assets/Textures/…

PS: enclose your code fragment, console log between ``` see how-to-type-code-blocks

The easiest way to add a sky to a scene is by making a new j3o in the SDK, right-clicking the root node and selection Add Spatial->Sky. Then when you load that j3o the sky is loaded with it.

I did that, but when I add the texture to the main scene, the sky does not show either…that’s why it occurred to me to add the sky as a separate scene, but that does not work too.

Okay,
Show youre code you are using now, and what is your sky texture?

Thank you that’s how the scene looks now.
