Texture Rendering

Troubleshooting graphics

Hello, ok so I am very new to jME and i am having great difficulty texturing my 3D objects…

Here is a class I'm working on in which I am using a gun object that I pre-converted to .jme format


package jmetest.Newbie;

import java.io.IOException;
import java.net.URL;
import java.util.logging.Logger;

import com.jme.app.SimpleGame;
import com.jme.image.Texture;
import com.jme.scene.Spatial;
import com.jme.scene.state.TextureState;
import com.jme.util.TextureManager;
import com.jme.util.export.binary.BinaryImporter;

public class Modeling extends SimpleGame {
   
   public static void main(String[] args) {
      Modeling app = new Modeling();
      app.start();
   }
   
    private static final Logger logger = Logger.getLogger(Modeling.class
            .getName());
   
   protected void simpleInitGame() {
      
      TextureState ts = display.getRenderer().createTextureState();
      ts.setEnabled(true);
      Texture t = TextureManager.loadTexture("/jmetest/Newbie/WW2 German Guns/mg34t.jpg", Texture.MM_LINEAR_LINEAR, Texture.FM_LINEAR );
      t.setWrap(Texture.WM_WRAP_S_WRAP_T);
      ts.setTexture(t);
   
        Spatial model = null;
        try {
            URL locale = Modeling.class.getClassLoader().getResource("jmetest/Newbie/WW2 German Guns/gun-mg34-3ds.jme");
            BinaryImporter importer = new BinaryImporter();
            model = (Spatial)importer.load(locale.openStream());
            model.updateRenderState();
        } catch (IOException e) {
            logger
                    .throwing(this.getClass().toString(), "wow you fucked up!!",
                            e);
        }
        rootNode.setRenderState(ts);
        rootNode.attachChild(model);
       
    }
}



This renders the gun just fine but there is no texture on it.  There are no error messages or anything so it seems to be loading the image correctly.  I can't even apply a simple one color MaterialState.  I'm really confused here..

Check if your model has texture coordinates. If it doesn't, they will default to 0,0 - and your entire model will be textured with the signel pixel at the texture's lower left corner.

You are also setting the texture state on the rootnode, not the particular mesh within the model.
