i have loaded OBJ with a material like 🙂
```
BABYLON.SceneLoader.LoadAssetContainer("models/raptor/", "raptor.obj", scene, function (_container) {
player_meshes = _container.meshes;
let myMaterial = new BABYLON.StandardMaterial("mat_raptor", scene);
myMaterial.diffuseTexture = new BABYLON.Texture("models/raptor/Raptor_Albedo2.PNG", scene);
myMaterial.invertNormalMapX = true;
//myMaterial.invertNormalMapY = true;
//myMaterial.bumpTexture = new BABYLON.Texture("models/raptor/Raptor_NormalMap.PNG", scene);
//meshes[0].material = myMaterial;
player_meshes[1].material = myMaterial;
player_meshes[1].setParent(player_meshes[0]);
player_meshes[2].setParent(player_meshes[0]);
player_meshes[3].setParent(player_meshes[0]);
player_meshes[4].setParent(player_meshes[0]);
player_meshes[5].setParent(player_meshes[0]);
player_meshes[6].setParent(player_meshes[0]);
player_meshes[7].setParent(player_meshes[0]);
player_meshes[8].setParent(player_meshes[0]);
player_meshes[9].setParent(player_meshes[0]);
// Adds all elements to the scene
_container.addAllToScene();
ready_play=true;
});
```
but
in blender is correctly
i tried
myMaterial.invertNormalMapX = true;
myMaterial.invertNormalMapY = true;
myMaterial.invertX = true;

Hi @gilberto_barbosa try
```javascript
scene.useRightHandedSystem = true
```
as Babylon.s is a left handed system by default.

I only ever inverted on Y, when I was creating KTX files. I have no doubt that these are working. Inverting Y has them right side up, & inverting X has them backwards. Think all you should need to do is stop inverting X.

Is your texture a .dds texture?
I had some problems lately with dds texture that was displayed inverted whatever I did and converting them to .png “fixed” the problem.

Think that is because, like a ktx texture, you have to flip it on Y when it is created. He does show that they are PNG’s in the code.

Even by setting the `invertY` parameter of the `Texture` constructor did not change anything:
`invertY = false`:
`invertY = true`:
If using a .png instead and not setting the `invertY` parameter (so it is `true` by default):
Note: if anyone wonders, it’s an asset from the game **Skyrim**
So, from these tests, it seems the .dds texture loader does not honor the `invertY = true` value, or there’s something in the .dds file that conflicts with the code…
But it is not the problem of the op, as you said he is using png textures.
[EDIT] Sorry for the OT, but if someone is coming here because of inversion problem with dds pictures: it’s because the inversion does not work for compressed textures (s3tc and such) - the `UNPACK_FLIP_Y_WEBGL = 1` gl flag does not work for such textures [/EDIT]

My texture is PNG, i will try :
scene.useRightHandedSystem = true

I don’t know what your requirements are, but if you can use glTF, these kinds of problems will be much less likely to occur as glTF is more strict on conventions.
