I’m encountering an issue with the Specular/Glossiness PBR material in JME3. When I use it without a normal map, my textures (BaseColorMap, specular, glossiness) appear as expected. However, as soon as I add a normal map texture, the other textures seem to become blurred or distorted.
This issue does not occur when I use the Metallic/Roughness PBR workflow; the normal map works correctly in that case.
Here’s a simplified example to reproduce the problem:
package gamecollectiontester;
import com.jme3.app.SimpleApplication;
import com.jme3.asset.plugins.FileLocator;
import com.jme3.light.DirectionalLight;
import com.jme3.material.Material;
import com.jme3.material.Materials;
import com.jme3.material.TechniqueDef.LightMode;
import com.jme3.math.ColorRGBA;
import com.jme3.math.Vector3f;
import com.jme3.scene.Geometry;
import com.jme3.scene.Node;
import com.jme3.scene.shape.Box;
import com.jme3.texture.Texture;
public class AnimePBRDemo extends SimpleApplication {
public static void main(String[] args) {
AnimePBRDemo app = new AnimePBRDemo();
app.start();
}
@Override
public void simpleInitApp() {
// Create box
Box box = new Box(1, 1, 1);
Geometry boxGeo = new Geometry("SpecGloss Box", box);
viewPort.setBackgroundColor(ColorRGBA.Cyan);
// Load material
Material mat = new Material(assetManager, Materials.PBR);
// Set required parameters
mat.setBoolean("UseSpecGloss", true);
mat.setTexture("BaseColorMap", assetManager.loadTexture("/Textures/cartoon_wood_base_color.png"));
mat.setTexture("SpecularMap", assetManager.loadTexture("/Textures/cartoon_wood_specular.png"));
mat.setTexture("GlossinessMap", assetManager.loadTexture("/Textures/cartoon_wood_gloss.png"));
// The problem occurs when this line is uncommented:
mat.setTexture("NormalMap", assetManager.loadTexture("/Textures/cartoon_wood_normal.png"));
// Apply material
boxGeo.setMaterial(mat);
rootNode.attachChild(boxGeo);
// Lighting
setUpLighting();
setUpPbrProbe();
}
private void setUpLighting() {
DirectionalLight sun = new DirectionalLight();
sun.setDirection(new Vector3f(-0.5f, -0.5f, -0.5f).normalizeLocal());
sun.setColor(ColorRGBA.White.mult(1.5f));
rootNode.addLight(sun);
}
private void setUpPbrProbe() {
ModelKey Key = new ModelKey("/LightProbes/Sky_Cloudy.j3o");
Node scene = (Node) getAssetManager().loadModel(Key);
LightProbe lightProbe = (LightProbe) scene.getLocalLightList().get(0);
lightProbe.setName("Default LightProbe");
lightProbe.setPosition(new Vector3f());
lightProbe.getArea().setRadius(10000);
getRootNode().addLight(lightProbe);
getRenderManager().setPreferredLightMode(LightMode.SinglePassAndImageBased);
}
}

I have verified that the texture paths are correct and the textures themselves are valid. I’m not sure if this is a bug in the JME3 shader, an incorrect material setting on my part, or something else. Any help would be greatly appreciated!
