solved Change texture on glTF model

[djeustice]

Hello.  I have this Seat.gltf model in my scene that I exported it from 3ds Max.  Anyways, how do I change the diffuse texture on it?  The seat imports with a black texture (SeatBlack_baseColorTexture.png).  I'd like to change it to this (SeatLime_baseColorTexture.png).   My goal eventually is to let the user pick from a variety of seat colors.  Any pointers in the right direction would be appreciated.  Thanks.

    var mySeat = BABYLON.SceneLoader.Append("./models/", "Seat.gltf", scene, function (scene) {
    }, null, function (scene) {
        
        var LimeTexture = new BABYLON.PBRMaterial("", scene);
        LimeTexture.baseColorTexture = new BABYLON.Texture("models/SeatLime_baseColorTexture.png", scene);
        mySeat.material = LimeTexture;
    });

Hello you can have a look at the PBR documentation here:

http://doc.babylonjs.com/how_to/physically_based_rendering

3dsMax is exporting PBRMetallicRoughnessMaterial: http://doc.babylonjs.com/how_to/physically_based_rendering#pbrmetallicroughnessmaterial

Based off of your small example it appears your texutre swap is happening in the incorrect place. It's happening in the 'Error' callback of the load method.  It should be in the first callback that you currently have blank.

This seems to be working for changing just the diffuse texture.  I'll take a look at exporting PBRMetallicRoughness from 3ds Max. Thank you kindly.

 

    var myKayak2;
    BABYLON.SceneLoader.ImportMesh("", "models/", "Kayak.gltf", scene, function (newMeshes)  {
        myKayak2 = newMeshes[0];
        
        var BWTexture = new BABYLON.StandardMaterial("BlueWave", scene);
        BWTexture.diffuseTexture = new BABYLON.Texture("models/BlueWave.png", scene);
        BWTexture.diffuseTexture.hasAlpha = false;
        BWTexture.backFaceCulling = false;
        myKayak2.material._subMaterials[2] = BWTexture;    
    });

hey @djeustice, what is ._subMaterials[2] ? I have not success to change texture from gltf scene. From a new material I got not UVs texture placement correct and change in live from DynamicTexture I have black texture. 

Here an exemple :

So @efxlab found a solution: The texture has to be loaded flipped:)
