Texture coords error when applying explicit material?

Troubleshooting General Help
1

hi, i’m new to jmonkey on android platform.
i have followed the beginner tutorial and successfully having the ninja model displayed on android.
but i have encountered a problem that ninja spatial displayed with wrong texture coords when i load a material and apply to it.

my source code is
Spatial ninja = assetManager.loadModel(“Models/Ninja/Ninja.mesh.xml”);
ninja.scale(0.05f, 0.05f, 0.05f);
ninja.rotate(0.0f, -3.0f, 0.0f);
ninja.setLocalTranslation(0.0f, -5.0f, -2.0f);

    Material unshaded = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
    unshaded.setTexture("ColorMap", assetManager.loadTexture("Models/Ninja/Ninja.jpg"));
    ninja.setMaterial(unshaded);
    rootNode.attachChild(ninja);

can anyone give me same tips to fix it, thanks .

it looks like the texture coords is flipped in y.

The texture has to be flipped.
you’ll have to use a TextureKey to load your texture (TextureKey is an AssetKey , AssetKey are just object that holds loading options for assets).
do that
[java]
Material unshaded = new Material(assetManager, “Common/MatDefs/Misc/Unshaded.j3md”);

//loading texture with a texture key
TextureKey key = new TextureKey(“Models/Ninja/Ninja.jpg”, true); //<-- true is for “flip the texture along the Y axis”
unshaded.setTexture(“ColorMap”, assetManager.loadTexture(key));

ninja.setMaterial(unshaded);
rootNode.attachChild(ninja);
[/java]
It should work

Are you solving the problem or asking how to unflip it?

thanks all, and i have fix it.
but i use the “false” param to make it works.

TextureKey texKey = new TextureKey(“Models/Ninja/Ninja.jpg”, false);

@nehon said: The texture has to be flipped. you'll have to use a TextureKey to load your texture (TextureKey is an AssetKey , AssetKey are just object that holds loading options for assets). do that [java] Material unshaded = new Material(assetManager, “Common/MatDefs/Misc/Unshaded.j3md”);

//loading texture with a texture key
TextureKey key = new TextureKey(“Models/Ninja/Ninja.jpg”, true); //<-- true is for “flip the texture along the Y axis”
unshaded.setTexture(“ColorMap”, assetManager.loadTexture(key));

ninja.setMaterial(unshaded);
rootNode.attachChild(ninja);
[/java]
It should work

oh?
I guess true is the default
